Ultimate Doom (walkthrough)

Ultimate Doom

First, before you start, you must pick the episode, and then your skill levels.
Here are the episodes and skill levels, and some other notes about the game:

Episode 1: Knee Deep in the Dead
Episode 2: The Shores of Hell
Episode 3: Inferno
Episode 4: Thy Flesh Consumed

Skill levels (from easiest to hardest):

I’m Too Young To Die (Skill level 1)
Hey, Not Too Rough (Skill level 2)
Hurt Me Plenty (Skill level 3)Ultra Violence (Skill level 4)
Nightmare (Skill level 5)

Beware the Nightmare skill level. It is not for inexperienced Doom players.
Enemies respawn, monsters are fast and powerful, but the good thing is you get
double ammo when you pick up ammo, and you can get a kill percentage over 100
too.

What I mean by double ammo is this: For example, when you pick up a box of
Shotgun Shells on skill levels 2, 3, and 4, it will add 20 shells to your
Shotgun Ammo, and 40 in skills 1 and 5. ID Software knows you’ll need the
double ammo in Skill 5. 😉

Notes: When you finish an episode, at the story text screen, you must press
Escape, New Game, and then the episode to start a new one. If you go on to the
next episode doing that (ex: Episode 2 to 3), you will lose your weapons you
had, your health, ammo, and armor. You would start out with a Pistol with 50
bullets, 100% health, and no armor.

Hint: Try to “telefrag” enemies. A telefrag is when you teleport using a
teleporter, and an enemy is on the spot where you teleport to, he will be
killed like that, without using any ammo to destroy it.

The Status Bar:

——————————————————————————-
   50   |   100%  | 2 | 3 | 4
|       |   
0%     |__|     
       
|

|          
|__|        OTHER AMMO
  AMMO  | HEALTH  | 5 | 6 | 7 | face) |  ARMOR    |  |     
——————————————————————————-
Ammo: You’ll see how many bullets you have for that weapon.

Health: Your survival. When you drop to 0% health, you’re dead.

Arms: Shows which weapons you have, the weapon numbers you have are yellow (for
example, if you have the Shotgun, just press 3 to get to it).

Your Face: The marine’s face. As your health goes down, your face will start to
bleed, and gets worse as your health slithers away.

Armor: Your armor helps you as it lasts.

The boxes next to armor: In each box, it will show which keys you have.

Other ammo: Shows how much ammo you have for each weapon, and shows how much
ammo you can hold up to for each gun.
——————————————————————————-
Now, here’s the walkthrough (note that this walkthrough is not useful for skill
level 5)! Also some enemies I tell you to kill in this game may not be there
because of the skill level so if you don’t see an enemy I told you to kill in
this guide, then you’re playing a low skill level.

Also, when you finish any episode, a story comes, then a little picture after.
Press Escape then New Game to start another episode. Or, press F7, then Y to
return to the title screen.

Episode 1: Knee Deep in the Dead
<><><><><><><><><><><><><><><><><><>

————-
E1M1: Hanger
————-

At the start, there is a health potion to the left and right of you. Go
straight and enter the room to the left, and beware the Shotgun Guys on skill
levels 4 and 5. Take their Shotguns, including the Combat Armor, health and
armor potions too. When you are done, leave the room, and head left into the
opening, and go through the door.

Kill all the enemies in this room, and watch out for the Shotgun Guys on skill
levels 4 and 5. When this room is empty, collect all the items and ammo here,
and go through the opening at the east part of the room.

Kill the Zombieman at the stairs, and collect the health bonuses, and go down
the stairs. Kill every enemy here, including the Imp(s) on the platform. Get
past the zigzag floor to the other side of the room. Before you open the door,
check the walls to the right until you find a secret area. In here, go down the
stairs and kill the Shotgun Guys on skill levels 4 and 5, and collect the ammo
and health here. Go outside and collect the Mega Armor, and go back to the zig
zag room, and now go through the door.  

Kill the enemies here, and get the health, and go to the exit door. But before
you go into the exit room, go back to the zig zag room (again). Remember that
platform that had the Imp(s) on it? It’s now been lowered. Go into the new room
that was behind the platform, and get yourself a Shotgun on skill levels 3 and
below, with a box of shells and health, and a Shotgun Guy on skill levels 4 and
5. Now go to back to the exit door, open it, grab the items, and hit the exit
switch.

——————–
E1M2: Nuclear Plant
——————–

Get out of the starting alcove and go right. You will be in front of a door,
but go left, and kill any Zombiemen there. Now check the wall across from the
wall in between the 2 doors until the wall opens. Grab the goodies in here, and
flip the switch (don’t forget the backpack), and leave this room. Take the door
to the left, and kill the Zombieman in front of you.

Go up the stairs, and while you’re climbing up, go through the opening to the
left when you see it. On skill levels 4 and 5, beware of all the nasty Shotgun
Guys here. But out here you can get a Soulsphere and a Chaingun and some
Chaingun ammo. Now go back through the opening. Climb up the stairs in front of
you, and when you get to the top, skill the enemies here, and get the Red Key
in this little room. Now go back to the room we started in.

Get to other side of the room, killing any Zombimen in your way. Go through the
Red Door. Kill all the enemies in front of you, and head straight, going up the
stairs. From the edge of the stairs, get to the other side of the room, and
collect the health and ammo, and go down the elevator.

Down here is an “ambush” of Imps and Zombimen. Kill all of them, even the Imps
on the high platforms. Hit the switch , and 2 doors will open. Take either one,
and go right down the stairs, and open the exit door. Kill the enemies, go down
the lift, and watch out for that nasty Imp there on hard skill levels, and hit
the exit switch.

E1M3: Toxin Refinery
———————

Open the door in front of you. Kill all the Shotgun Guys, Zombiemen, Demons,
and Spectres (on high skills) in here, and go left, following the hallway into
a door. When you open it, shoot the barrel to see those 2 Zombiemen go to
waste. Go right up the stairs, and take a left, going down some stairs. Down
here, kill the Shotgun Guys and Imps to your left. When they are all dead, go
left where they were and hit the switch.

Go back upstairs and to the right. A new passage in this room has opened. Go up
the stairs, killing any enemies in your way. Leave the room once you do (down
the stairs), and go back up. As you are getting up the stairs, you should hear
the sound of an elevator. Here’s a little map where the sounds are coming from:

| X   |
Say the X is you. The sounds are coming from A1, and A2, which are the
platforms in front of the “computer wall”. Run to A2 first (get on the platform
that dropped, and walk to the “computer wall” and it should open. Go
downstairs, and kill any Imps there. Hit the switch on the pillar and get the
Soulsphere when it comes down. Go back, exit A2, and run to A1, and do the same
thing as last time (kill the Imps, Demons, and Shotgun Guys in your way). When
it does open go straight, kill any Shotgun Guys or Imps  here, and get the
Rocket Launcher and Armor. Go right, jumping in the toxic river, entering the
slime tunnel.

When you get to the end, hit the switch, get the backpack, and check the walls
to the right of the switch until the door opens. Go inside, get all the goodies
in here, hop on the elevator, and check the wall at the end of the room, and it
should open. Grab the stuff in this room, and take the lift down, and go back
up the stairs from this familiar room. Go right again, open the door, and cross
the new bridge made. When you get to the wall, it should open.

Walk up and kill the Imp in front of you, and walk straight, and the wall
should open, revealing Zombiemen and Shotgun Guys. Kill them all, walk straight
and another wall should open, revealing Imps. Kill all of them, and go into the
room they came out of. In here, go through the opening, and follow it to the
exit door. Open it. In here, check the wall to your left, and it should lower
like a lift. Get on it, and ride it to the top. Kill the Imp up here, and get
the Box of Rockets.

Now turn back around and drop down to the exit room. Down here again, hit the
exit switch (this takes you to the secret level).

——————–
E1M9: Military Base
——————–

At the start, collect the two clips to the left and right of you, and get out
of the alcove. Kill all the Imps in the Imp Cage, and kill any
Zombiemen/Shotgun Guys that come for you. Take the staircase to the left of the
starting alcove, go down, and kill all the enemies down here. Walk around the
cage to get the Yellow Key.

Now go back upstairs and take the staircase to the east and go down. When you
get to the bottom, go left, down the stairs to the Yellow Door. Kill all of the
Zombiemen, Shotgun Guys, and Imps in front of you, and get the Red Key in this
room. Watch out for the opening wall revealing Shotgun Guys too.

Exit the Yellow Door we came from, and get to the other side of the room to the
Red Door. Open it, and kill all the Zombiemen, Shotgun Guys, and Imps, and then
go to the other side of the room and enter the little alcove. Destroy the
barrels (stay at a safe distance), and hit the switch.

Go back out the Red Door we came from, and a little Demon Pen has been
released. Get the Demons out of the way, and collect the Blue Key from the
Demon Pen. Go upstairs from this room, and take the staircase across from us.

Open the Blue Door, and kill any Zombiemen, Shotgun Guys, Imps, and Spectres in
this room. When you’re done, jump into the slime pit, and take either way to
this switch. Activate it, and go right from the switch, and this door should
open. Go through it, kill all the Imps, and take the lift up. There may be
another Imp there, so watch out, collect the health. Check the wall in front of
you, and it should open. Go across the new bridge, get the health in front of
you, and exit the level.

———————-
E1M4: Command Control
———————-

At the start, go to the door, but check the wall to the left and it should
open. Take the backpack, health, and Shotgun Shells, and go back out to open
the door.

Kill the Zombiemen to the left, and take the middle opening in this room. Kill
the Zombieman in here, and hit the switch and a lift should lower. Take it up
and go right, and walk up to the doors in this room. They should open by
themselves. Go in, kill the Imps, grab the health bonuses and Chaingun, and
pick up the Blue Key. If you are locked it, stand on the light the blue key
wason, the doors will open. Get out of this room.

There are 4 ways out of this room. Look for the entrance that has white lights
to the left and right of the opening. When you do, go in and go left. Kill the
Shotgun Guys here, and enter the Blue Door.

Watch out for Imps and Demons in this maze (try to kill them if they get in
your way). To get out, go right until you hit a wall, and go right again into
this little small room. Take a left, and go left again, and you’re out of this
maze. Turn right to get some health, armor, and the Yellow Key. Go up the
stairs in this room, and hit the switch next to the Yellow Door. Open the
Yellow Door, go right, go left, and then left again up the stairs, and cross
the bridge to the exit door. Open it, and hit the exit switch.

—————–
E1M5: Phobos Lab
—————–

Go across the slime pit, and in this room, go all the way right (there is a
door, but skip it) , and at the end, turn left into a “balcony”, and a platform
across from us should rise. Leave the room, kill any enemies in your way, going
straight. Keep going until you find a staircase to your right, and then climb
it. Destroy the 2 barrels and check the wall they were in front of. In this
secret room, grab the Shotgun, the ammo, and the health and armor bonuses. Get
out and go right onto the new bridge, and follow it to an opening. Kill the
enemies, and go forward to get the Health and Yellow Key. Leave this room and
jump into the slime pit, go straight, check the brown wall, and it should open.
Collect the armor, Rocket Launcher, and ammo, and go into the opening. Go
straight, collecting health and ammo, but when you try to pick up the small
Shotgun Shells in front of the wall, the wall should open, and get out of this
secret room.

Back in this familiar room, kill any appearing enemies coming from the door.
Now open the door. Kill all enemies here, and when you’re done, open the Yellow
Door. Take the lift down, and kill any enemies there. Go either left or right,
there’s no difference, but watch out for the doors that open, containing
enemies. When you’ve reached the other half of the room, jump in the acid, run
across it, and hit the switch, and then two pillars with enemies will lower.
Kill them, and get back to (and open) the Yellow Door.

Run across to the new opening, killing the enemies in your way. At the top of
the stairs, turn left and kill the enemies, and grab the health if necessary.
Go up another set of stairs killing all of the enemies. In this room is a
switch (which is a door), but before you open the door, check the walls to the
right of the door until you find a secret area. In this secret area, there’s a
Chaingun, Health, Backpack, and a Computer Area Map. Now go to the door.

Watch out in this semi-dark hall. Follow it, killing the enemies, and at the
end of the hall is another room. Kill the enemies, grab anything you need,
including the Blue Key. Hit the switch, turn around, go down the stairs, kill
any Spectres that should be there, and enter the Blue Door.

Be careful in this dark room….actually you don’t need to! There are some
Light Amplification Visors in here, and I’ll show you where they are:

 |
A                
|      |—|
 |——————-|  

So say you’re the X, and the Visors are “A”. At the start of the Blue Door,
turn left, and looking to the left, look for an alcove. This is an easy to miss
alcove, so watch out. So turn left when you see it, and follow the passage to
the Visors, along with so other goodies. This does count as a secret too.

When you are done with that, get to the northern half of the room, killing all
enemies in your way, and open the exit door. Kill the Demons there on skill
levels 4 and 5, and then hit the exit switch.

————————-
E1M6: Central Processing
————————-

Go straight down the hallway at the start, and when you get to the first 4 way
intersection, go right, and kill the enemies in your way. Enter the room,
destroy all the barrels (always stay at a safe distance), and look around this
room for the Red Key. Once you pick it up, you will be locked up in this room
and be ambushed by a bunch of monsters for a certain amount of time. While
waiting for the doors to open, kill the enemies, grabbing ammo and health while
you’re at it.

Once the door opens, Go all the way straight to the red doors (watch out for
any remaining enemies), and open either one. Follow the hall from the door you
took to a larger opening, and go through to get the Blue Key. Instead of going
back to the Red Door, jump into the slime pit and go left, and get on the
ledge, and grab health and other neat things. On the same ledge, go into the
alcove, follow it to the stairs, go up them, and grab everything in here. Hit
the switch (it is a door), and forward to the 4 way path. Go straight, opening
the door.

Turn right, follow this hall to another room to the right, and go into the
room. Get to the Blue Door. Touch it, but don’t open it. Look behind you to the
left: a platform with enemies behind it is lowering. Kill all the enemies
behind the lowered platform, and go in the small dark room behind the lowered
platform. Check the wall in between the Medikit and Radiation Suit, and you
should find a secret area, which has a Backpack, Rocket Launcher, and an
Invisibility Sphere. Open the Blue Door here (it’s a wall, actually), and kill
the Imps here, and get the Yellow Key (this was a QUICK shortcut to the Yellow
Key) and another Backpack. Follow down the hall until you here an opening, and
run back to the Blue Door (you won’t see the lights this time, but it’s still
here), open it, grab the Radiation Suit (if you haven’t yet), and go straight,
into the alcove in the slime pit, killing the Imps. Follow this alcove to a
door and some goodies. Open the door.

On Skill levels 4 and 5, there will be a whole bunch of Shotgun Guys here. Kill
them all, jump down there, and take their Shotguns. Also, check the platform
the Soulsphere is on. It will lower, and grab it. Stay on the platform, and
when you get as high as it goes, check the green wall and it should open. Get
into the room killing any enemies, and then go straight, and then go right,
going up the stairs. Kill the Imps up here, and hit the switch. Go back
downstairs, turn right, and go into the slime pit into the door. Kill the
enemies at the door. In this room, there are 3 staircases. Take either the left
or the right one, and follow the halls into another room.

In this big room, kill all the enemies in here. Then go into the small alcove
and hit the switch. Behind you is a big ambush of enemies. You can kill them,
or try to avoid them and run into the alcove in the northeast part of the room.
Open the exit door, collect the health here, and hit the exit switch.

———————–
E1M7: Computer Station
———————–

At the start, collect the ammo here, and open the door. Kill all the enemies in
your way, and from the door, go left, and follow the hall to a bigger room. Go
into the alcove, and take the lift up. Kill all enemies in your way, and follow
this ledge into a dark room. Grab the health, kill the enemies here, and take
the Yellow Key. Get back out, jump off the ledge, and go straight (not up the
stairs) to the Yellow Door.

Open the Yellow door, killing any enemies in your way, going straight. At the
end, go left, and go all the way straight, and at the stairs, destroy the
barrels, and kill the Zombiemen there. Go up the small set of stairs, and kill
the Shotgun Guys from the pillar that lowers. There are two passages to take:
take the one on the right, and kill the enemies in your way. Go straight until
you get to the door, and open it.

Kill any enemies that are there, and get the Northwest part of the room, and
take the lift. Grab the health if you need to, and when the lift reaches the
top, follow this hallway to the Red Key, killing enemies. Once you get the Red
Key, backtrack your steps to the lift, and take it down. In this room, avoid
the new enemies, running to the door. Run straight out of this room too, and
get past the pillar down the stairs, keep going straight, and get back to the
Yellow Door.

Open it, go left, and take another left up the stairs. Go straight to the other
set of stairs, and descend them. At the bottom, go right all the way, then turn
left to the Red Door. Open it, kill the Imps if you haven’t and go straight to
get the health and the Blue Key. Leave this room. Go all the way right to the
Yellow Door, skipping the new alcove. Go right until you see the Blue Door, and
open it.

Kill the enemies in your way, and go up the stairs. In this room, go straight,
into another room. Follow its hallway to another room, killing the enemies in
your way. In this dark room, hit the switch, and leave this room, going into
the room near the Blue Door. On the other side of this room, a door has been
opened. Go into the new room, kill any enemies in your way, go through the exit
door, and hit the exit switch.

E1M8: Phobos Anomaly
———————

You’ve made it to the final level of episode 1! Anyway, hit the switch at the
start, and the wall will lower. From where you are, shoot a barrel and watch
many of the Demons die. Kill the leftover ones, and get off the platform you’re
on, and turn left down the stairs. While going down the stairs, check the walls
to your right, and you should find a hidden Soulsphere. Now, enter the door at
the bottom.

If you need ammo, there is some Shotgun and Chaingun ammo in the rooms to the
left and right, but watch out for the Demons there on hard skill levels. Now
get out of the room you are in, and get to the other end of the room (from the
door). Hit the switch, and take the lift.

Walk up forward, and 2 doors will open, both will have 1 Baron of Hell. Here
are some tips for beating them:

1. If you have plenty of Rocket Ammo, use it on them, no matter how many
rockets you have.
2. Watch out for the Spectres on skill levels 4 and 5. Get them out of your
way.
3. Run around the room, taking potshots now and then.
4. If you find you are low on ammo, you can lure them to the barrels, and at
least damage/kill one.
5. On skill levels 4 and 5, you can have the Spectres get in a fight with a
Baron to weaken him (the Spectre needs to be hit by one first though).
6. The Barons will respawn on skill level 5, so finish them off quickly.

Once you’ve defeated both Barons, the walls will lower. Jump down to the lower
ground, and down there is a “building”. Hit the switch on it, and the stairs
will rise. At the top, take the teleporter, let the enemies kill you inside,
and you’ve beat episode 1!

Once you die (you have to), you get a little story:
——————————————————————————-
Once you beat the big badasses and clean out the moon base you’re supposed to
win, aren’t you? Aren’t you? Where’s your fat reward and ticket home? What the
hell is this? It’s not supposed to end this way! It stinks like rotten meat,
but looks like the lost Deimos base. You’re stuck on the Shores of Hell. The
only way out is through. To continue the Doom experience, play the Shores of
Hell, and its amazing sequel, Inferno!
——————————————————————————-

A few seconds after the story is over, you’ll see a screen of the id software
employees, who make this game, and what they did (level design, music, etc).
After that, press escape, select New Game, then pick the Shores of Hell. Select
your skill level, and you begin Episode 2.

E2M1: Deimos Anomaly
———————

You start out in an alcove. Get out and go right, skipping he teleporter (but
grab the Shotgun that’s there on skill levels 1 and 2 next to it though). Kill
the Zombiemen in your way, and pass the evil red cross, going right. Kill the
Zombiemen here that appear on skill levels 3 and above, and grab the Medikit
and Blue Key here. Go through the teleporter we skipped.

Kill any enemies in your way, and head straight, on skill levels 3 and above,
grab the Shotgun on one of the red triangles, Continue through more of the
room, killing any enemies in your way. Cross the red blood pit, and hit the
switch on the right wall. A little lump with a switch on each side behind you
will rise. Hit the switch on both sides, and go through the last teleporter we
visited. From here, go past the red cross again go right, and go through the
new teleporter here. In this room, kill all enemies (watch out for the
Cacodemon on skill levels 3 and above), and once the room is cleared, grab the
Plasma Gun and Cell Pack here. Leave this room, go through the teleporter near
the start, and go across the blood pit (don’t go to the teleporter yet).

To the left of the teleporter is a small opening. Enter it, and in this small
hallway, collect the health and Red Key. Exit this secret room, and now go
through the teleporter. In this room, go through the small alcove in the left
wall, and flip the left switch. Where the switch we flipped is, a secret area
will appear (this only happens once), and enter the teleporter in the secret
room.

Rush through this secret hallway, collecting the armor and health bonuses, and
go through the teleporter at the end of the hall. If the secret door closed,
hit the switch to open it. Now hit the other switch we didn’t flip yet. Leave
this small alcove, to find that a platform is lowering. When it does lower,
kill the enemies there, and when it is clean, go straight, and enter the Red
Door. Kill the enemies inside, and grab all the goodies here, and leave this
room, going straight to the Blue Door. Open it, and take the teleporter.

Kill the enemies in here, and grab the health in here. Hit the switch in this
room, and the stairs will raise in the alcove. Kill the Lost Soul/Cacodemon
there (skill level varies), climb the stairs, hit the switch, and exit this
alcove. Go through the new teleporter that lowered, and enter it.

Walk forward, and the wall in front of you will lower. Watch out for the
Cacodemon on skill levels 4 and 5. Kill it, or avoid it, open the exit door,
kill the Imp there, and hit the exit switch.

———————–
E2M2: Containment Area
———————–

Grab the armor in the right alcove if you need to. Go straight, killing the
Imp, and then flip the switch on the left wall. Turn around, and find that the
crate containing the Shotgun/Ammo (it’s ammo on skill levels 1 and 2, and a
Shotgun on skills 3 and above, but the Shotgun on skills 1 and 2 is in the
alcove behind the crate with the Ammo) has lowered. Take whatever’s there, turn
around, go straight, and when you have the choice to go left or right, go left.
Go straight to the Berserk pack across from us, and go right, killing any Imps
in your way. Enter the non-crate room.

You can easily outrun these Imps in here. Get to the other side of the room,
and just before the door is an alcove with a switch on the left wall. Flip it,
and the door we were just at has opened. Go through it, and go forward inside,
and stairs to the platform will rise. At the top, go straight, to the other end
of the room. Again, when you have the chance to go left or right, go right. Go
all the way straight and when you see the exit door, don’t jump into the slime
pool in front of it. Kill any enemies in your way. When you see the exit door,
you can’t access it, you’ll need to hit a certain switch first. From our view
of the exit door, go left, go left again past the Red Door, to the crushing
ceiling hallway. Oh no!

There may be enemies in front of us, but let them commit suicide under the
crushing ceilings. Timing your moves right, get to the other end of the
crushing ceiling hall. Now, follow this hallway to a slime pool. Cross it to
get the Blue Key. From the Blue Key, there’s an alcove to the right wall. Climb
down the stairs, and open the Blue Door, and kill the Spectre there on hard
skill levels. Go through the Blue Door, and go right, and open this Blue Door.
Walk forward to get the Red Key. Leave this room, go back through the other
Blue Door, and backtrack your steps to the Red Door.

Open the Red Door, turn right, take another right, and flip the switch. Watch
out for the Imps though. Leave the Red Door. Now, a bridge is rising to the
exit door. Cross it, open the exit door, and hit the exit switch.

E2M3: Refinery
—————

There’s a door to the right, but skip it, and go straight. At the Cacodemon
cage, turn left, and then right. Go through the opening, turn left, and kill
any Zombiemen there. From the Blue Door, go right, and go straight until you
hit a wall. Turn right, go straight, take another right, and kill the Imps and
Demons there, and go straight. Before taking a turn into the pillar room, check
the green walls across from it. Use this map to nail it down:

Once you do find the secret, walk in, turn right, cross the slime pit and pick
up the Backpack. Exit this secret room, and no go into a pillar room. Instead
of crossing all those rising and dropping pillars, check the walls to the left
when the entrance of the room. A wall should rise, go into this room, and kill
the enemies in here. From where we entered into this room, go right, and pick
up the Shotgun on the platform. No go straight (not to the slime pool), turn
left, and take a right into a room. Now go straight, jump into a blood pit, and
go right onto a platform. Kill any Lost Souls here, and grab the Plasma Gun and
its ammo. Jump off the Platform (not into the Blood Pit), and kill the Demons
here. In this room, behind the pillar is the Blue Key. Leave this room, but
watch out for the Baron on skills 4 and 5. Once you leave the room, turn right,
and at the end of the room, turn left, and go straight, into the big room
across from us. At the end of the room, search the wall that’s in between 2
gray skinny poles (the one on the right), and the wall should open.

Go into this room, go straight, and when you reach the wall, go left to the
Blue Door. Open it, kill any enemies in your way, and go right, through a dark
hall. Follow it to a bigger room, kill any enemies in your way, and collect all
of the goodies in the bigger room. In the northwest part of the room, enter
into a dark room. I’ll show you the quickest way to get out of here: From the
start of this pillar room, go all the way right until you hit a wall. Then, go
left until you hit another wall. Go right until you hit another wall. Then go
left, and to the right is the exit out of this room. Cross the slime pit, turn
left, and then go right into another room. Kill any enemies here, enter the
exit door, and hit the exit switch.

—————–
E2M4: Deimos Lab
—————–

At the start, check the flashing wall to the right, and it should open. Go into
this secret area, and collect all of the goodies in here. Leave this room, go
right, and go through the teleporter. In this room, go through the opening in
the left, and rush to the opposite wall. Go right, left, and then straight,
skipping the opening to the right. Now go left, kill the Imps here, and open
the door. The enemy in front of you varies: Demon on skills 1 and 2, a Baron on
harder ones. Avoid or kill the enemy, and at the left side of the room, flip
the switch, and take the lift to the left of it. Ride it to the Blue Key. Jump
off the platform, and exit this room.

Go straight, and then right. Now go left into the opening we skipped. From
here, run to the Blue Door Across from it. Enter it. Follow this hallway to the
Yellow Door, but since we don’t have the Yellow Key, go left. Run under the
crushing ceiling to get the Yellow Key. Return to the Yellow Door, and open it.

From the Yellow Door, go left, passing the staircase. After the staircase, hug
the left wall (still move, don’t stay in 1 place) until you drop into a small
pit. In this small pit, check the walls until an opening is revealed. Get the
Plasma Gun in this secret room, and take the teleporter. If you’re playing on
skill levels 3 and above, use your Plasma Gun to kill the Cacodemon in front of
you. After that, kill the other enemies, and go through the alcove in the
northwest part of the room. Keep going straight until you get to a
bigger room, and once you get to the bigger room, run to the teleporter across
from you.

Once you’ve entered the teleporter, go right, kill the Demon, and jump into the
blood pit, and go left, onto a platform (DON’T ENTER THE TELEPORTER YET!), and
hit the switch near the teleporter (there’s only one). Now enter the
teleporter. When you get back to this room, go forward, but go back into the
teleporter. Go right again, onto the new bridge to the exit door, Open it, kill
the Imps, but don’t hit the exit switch yet. Turn around, cross the new bridge
leading to the Soulsphere, and grab it. Now go back to the exit door, open it,
and hit the exit switch.

———————
E2M5: Command Center
———————

At the start, open the door, and kill the enemies. Take the staircase at the
southeast part of the room, and climb it. At the northeast part of the room,
hit the switch (it’s a door), and go through into this room. Follow the hallway
to a switch (another door), open it, and go through it. In this room, open the
door to the right, and kill the Demons inside. Go into the room, and hit the
switch in the small alcove. Leave this room, and turn right. At the wall, turn
another right, to see that the stairs have appeared. Climb them, go through the
red wall (just walk through), and take the teleporter.

Watch out for the Lost Souls in this room. Kill them if you can, and try to
open the door in this room (it’s a switch). When it opens, get to the exit door
on the other end of the room, and hit the exit switch (this exit leads to the
secret level ;)).

————————–
E2M9: Fortress of Mystery
————————–

Run straight to the wall at the beginning and pick up the Plasma Rifle (equip
it too). Turn around and blast down the 4 Barons. When they’re all dead, grab
the goodie from each alcove (there’s a Shotgun, Chaingun, Rocket Launcher, the
Plasma Gun we got, Chainsaw, Backpack, and Computer Area Map, grab everything).
Open the door in one of the alcoves, and go into the room.

Use your Rocket Launcher and Plasma Gun to kill all the Cacodemons in here, and
when the room is empty, collect the health and ammo, then the Soulsphere. From
the door we entered, check the wall across from it (the wall in the room with
all the Cacodemons), and it should open. In this room, flip the switch to the
left and the door to the right of it will open. Enter it and get the Blue Key.
Exit it, open the Blue Door and get the Red Key. Exit that room, and enter the
Red Door to get the Yellow Key. Open the Yellow Door and go through the exit
teleporter.

Tip: If you don’t have enough ammo, lure the Barons of Hell and Cacodemons into
one room, and have them fight off each other. You can then kill the remaining
enemies easily.

————————–
E2M6: Halls of the Damned
————————–

Go into the other room at the start. Kill any enemies here, and grab the Rocket
Launcher. Open the door in here. Kill the enemy in front of you (if one is
there), and hit the switch. Leave this room, and go back into the room we
started in. Go past the new opening and go right. Go all the way straight, past
all of the pillars, and hit the switch when you get to it. A platform to the
right of it will rise, and use that platform to get to that Berserk Pack. Take
it, and see that the platform around the pillars have lowered to just a slime
pit. Get off the platform you’re on, and RUN through the new opening in the
western part of this room. Follow it to a switch and some health. Once you hit
the switch, get out of this room, go left onto a platform, collect the health,
and go left into a new opening, where there’s a Blue Door, and to the right is
a normal door. Go through the normal door, having a Shotgun or Chaingun ready.

Go all the way straight, killing any Zombiemen/Shotgun Guys in your way. When
you have the choice to go left or right, go left. Go straight, and go left to
get the Blue Key. Turn around, go right, then all the way straight (skip the
hallway to the left as we progress), until you get to a brown opening. Go
inside this dark, brown room (this is a maze if you were wondering). I don’t
know the exact guide to the door in here, but all I can tell is look around
until you find a door in here, and kill any enemies in your way. Once you find
the door, go through it, and go right, going through a hallway. When you get
out of this hallway, go left, and take another left to a small room, and in
here, and go left, and get the Red Key. Exit this small room, and backtrack
your steps to the door, killing any enemies in your way. Go back through the
door, and work your way out of this maze. When you do get out of this dark maze
(to the bright white halls again), go left, and on this part of the hall are 3
doors to the left. Each door is separated by a wall. Take the second one.

Use a Shotgun or Chaingun to blast the Zombiemen/Shotgun Guys/ in front of you.
Follow this hallway to another door. Open it, go into this small room, and hit
the switch on the right wall. A new passage behind you has opened. Go through
it. Follow the long hallway to another room. On hard skill levels there will be
a Cacodemon in this room. Kill it, and open the door that has a Health Bonus
in front of it.

In here, take either path to the other end of the room, and at the other end of
the room is the Yellow Key. Take it, exit this room, and back in this room,
Imps have been released. Take a left, through this same long hall again,
outrunning these enemies. When you wind of in front of the switch you hit, take
the door on your right, follow the hall to the other door, open it, and turn
right. Now, kill any new appearing Demons or Barons (on hard skill levels) in
your way. Go left past the opening to the maze, keep going straight, and then
as you go keep on heading straight, take a left to another hallway. Run
straight to the door, open it. To the right, open the Blue Door. Go inside and
open the Red Door. Go inside and open the Yellow Door. Go inside and hit the
exit switch.

——————–
E2M7: Spawning Vats
——————–

At the start, you’ll see two openings to go through. Take the one on the left.
Follow this hallway into another room. When you do get into the a new room, go
straight into another room, skipping the door on your right. In this room, kill
the Imps in here, and go right, heading down the stairs. In this large room,
kill all the Demons in here. Grab the goodies. In the southeast part of the
room, there is a lump with a switch on it. Hit it, and the lump will lower. Go
through the hall into a bigger room. Kill the Cacodemon(s) and a Baron in here
(that only appears on hard skill levels). In this room, take the health, and
get the Blue Key. Now backtrack your steps back to the room we started this
level in.

In the room we started in, take the other opening we didn’t go through. Follow
the hall into another room. In this room, open the Blue Door. Kill the Demon in
front of you, and go right and get the Chaingun. Now turn around, go straight
(not up the stairs), and go through the opening to the left of the staircase.
Kill any enemies here, and go up the stairs in the room. Follow the staircase
to a platform with the Yellow Key.

From where you are, kill the Imps in front of you. When you do, hop off the  
platform and go through the opening north of the platform you just jumped off.
In this room, go left, and open the Yellow Door to your right. Go into the room
killing any Imps. From the Yellow Door, get all the way to the other end of the
room, and open the door to the right. Kill the Imps in here, and enter the
alcove near the pillar. Follow the small hall to a switch, and hit it (kill the
Imp in here too). Now, exit this hallway to see the pillar has lowered. Get the
Red Key on it. Now leave this room and go left, out the Yellow Door. Out here,
go left, and then when you get to the “rectangular” hallway, go left, and when
you get to the wall, go right, and open the door. In this room, open the Red
Door to your right. Go inside, and hit the switch on the right. The switch will
disappear, and hit the new one. Leave the Red Door, kill the Cacodemon, and
take the bridge rising to the exit door. Open it, and hit the exit switch.

———————
E2M8: Tower of Babel
———————

Congratulations, you’ve made it to the final level of episode 2! Anyway, at the
start, turn around, and hit all 4 switches on this pillar. Walk up to 1 of the
sets of the rising stairs, and walk up to the wall the staircase leads to. It
will open, and go inside and grab the goodies. Take out your Rocket Launcher,
then go outside and KILL THE CYBERDEMON! Also, his exact location is the
northwest part of the map. Here are some hints:

1. When facing the Cyberdemon, Strafe to avoid his Rockets.
2. Watch out for the Lost Souls on skill levels 3 and above. You could try
luring them in a fight with the Cyberdemon.
3. If you need health or ammo, go into the other power-up rooms, then go back
out to kill the Cyberdemon.
4. Use the Rocket Launcher. It’s your best hope.
5. At each corner of the map there is a pillar bigger than all the others that
is right next to the wall (they don’t touch the walls, so there is a small
crack between the pillar and the wall). If you are on one side of the crack and
the Cyberdemon is on the other, you can shoot through the cracks with your
Chaingun or Shotgun, and his Rockets won’t pass. This takes a while, and do not
touch the crack when the Cyberdemon fires his rockets, or you’ll get damaged.
6. Pillars are scattered all around the map. You can hide behind one when the
Cyberdemon fires.
7. There are also 4 power-up rooms, and each contain Boxes of Rockets, 2 of
them have Soulspheres, and 1 other one has a Rocket Launcher. Use them when you
need to.

Once you defeat the Cyberdemon, congratulations!

Then, you get a little story:
——————————————————————————-
You’ve done it! The hideous Cyberdemon lord that ruled the lost Deimos base has
been slain and you are triumphant! But… where are you now? You clamber to the
edge of the moon base to see the awful truth. Deimos floats above Hell itself!
You’ve never heard of anyone escaping from Hell, but you’ll make the bastards
sorry they ever heard of you! Quickly, you rappel down to the surface of Hell.
Now, it’s on to the final chapter of Doom! – Inferno.
——————————————————————————-
A few seconds after the story is finished, you’ll see a screen of what the moon
base looked like. Press Escape, select New Game. Now pick Inferno, select any
skill level, and you start Episode 3.

<><><><><><><><><><><>
Episode 3: Inferno

—————-
E3M1: Hell Keep
—————-

Hit the switch in front of you at the start. Then, when the platform lowers, go
to the door across from you. To the left and right of the door are switches.
Hit the one on the left, and the door will open.  Go through the door, and turn
right. Open the door, and kill the enemies in here. Then from the door, go
right and open another door. Follow the hallway to another door, killing any
Demons. When you get to the door, open it, and open the door across from you.
Kill all the Imps in this room, and the next door is the exit door. Before you
open the exit door, check the walls to the left of the exit door until you find
the secret. In the secret room, there is a Stimpack, Shotgun Shells, and a
Rocket Launcher. Now open the exit door, collect the health and ammo in here,
and go through the exit teleporter.

————————
E3M2: Slough of Despair
————————

At the start, keep to the left hand wall and just keep running along it until
you get to the Blue Key. Then turn around, go straight, and when you’re out of
the alcove, take 2 lefts into another one. Walk up to the wall in front of you.
Kill the Lost Souls that were behind the wall (or avoid them), and go into the
room they were in. Open the Blue Door in here, hit the switch, turn around, go
right, grab the health and ammo, and get to the exit teleporter.

——————
E3M3: Pandemonium
——————

On skill levels 4 and 5, there will be a Demon in front of you. Kill it,
otherwise get out of your starting alcove, turn left, and then right up the
stairs. Kill the Imps in here, hit the switch on the north part of the room,
and the pillar behind you will lower, containing the Shotgun. With your back
against the last stairway you took, go straight, and then take a right, going
up a different set of stairs. Up here, go right, and work your way around over
here until you see a pit below you. Jump in it, go straight, down the stairs
into a Silver Room. Go right and grab the ammo and the Blue Key. Now head back
up the stairs, and hit the switch in this pit. Then the floor you’re on will
rise (don’t jump off). At the top, take a left, and jump back into this
familiar room (the room where we got the Shotgun).

Now, with your back against the stairs we took to get up here at the start of
the level, go straight, and then left up the only staircase we didn’t take. Up
here, go right again, and then work your way around until you find a pit below
you. Jump in it, go straight, and collect the health. No go down the stairs in
this ledge, avoiding the opening to the right as you progress. At the bottom is
a Invincibility Sphere. Take it, go back all the way up (skip the opening),
back into the pit. Now kill the Lost Souls and Shotgun Guys here, and look
around the other areas in this pit until you find a BFG (YEAH!!), and a
Soulshpere. Now go down the staircase again, and go to the opening we skipped.
Then go all the way right, killing any enemies in your way. At the door you’d
stop at, turn left up the stairs, and kill the Imps in here. In this room is a
gray platform that has a ledge you can step on. It can trigger a secret. Here
is a map to show how to open it up:
                                   
|
         
|    X   
|              
|  <– Blue Door
         
|———|              
|
       |–|_________|–|            |
      
|_______________|           
|  

Say the X is you. Get on the small ledge, and walk forward. A wall in front of
you should open. Kill any enemies that appear, and grab the goodies behind the
wall that just opened (the ledge is the — part, and you walk up to the ___
part that’s shorter, and the other ___ part is another ledge).

In this room also is the Blue Door. Open it, and go inside. Kill the Imps in
here, and then open the exit door. In here, walk up to the exit teleporter.

——————–
E3M4: House of Pain
——————–

Collect the Rocket Launcher and Rockets in this starting room, and go straight,
heading up the stairs. Once you get to the top, just follow the hallway to a
door. Open it. Follow this hall to a bigger room, and kill all the enemies in
here from where you are. Then, run up to the 3 switches in this room. Hit the
one in the middle, and turn around to see a platform rise (it won’t if the
crushing pillar has lowered into the pit), and collect the Chaingun and
goodies. Then, go back and hit the switch on the left, and turn around again
and see a platform rise (like I said before, it won’t rise if the crushing
pillar has lowered into the pit). From the new platform that just raised,
collect the Invincibility Sphere and health. No go back and hit the switch on
the right. Then enter through the opening to the right of it. Follow this hall
to another opening.

Go through the opening, and go straight. Go through the next opening, and then
go all the way straight in this large room (skip the two large openings to the
right), and then there will be another opening to your left. Skip it, and go
into the opening we’re heading to. Kill the Lost Souls and the Baron that
appears in here on skills 3 and up, and get the Blue Key in this opening we’re
in. Then turn around, get out of this opening, go right, and take another right
into the opening we skipped. Get to the other end of the room to the Blue Door.
Open it.

Kill the Imps in this room, and go straight, opening the door (across from the
Blue Door, not to the left, the wall across from the Blue Door is a door).
Then take a left, and in this room is a blue square. Step on it a few times,
and a door should open that we can’t open on our own. When the door is open,
run through it, and go right. Follow this hall to another room, turn right,
kill the Imps in here, and run to the pillars that have switches. Go to the
pillar on the left, and hit the switch on the west side of the pillar. Turn
around, go right until you bump into a wall, and turn right again. Go through
the opening we just opened, and get the Yellow Key. Now go back, and hit the
west switch on the right pillar. Now go straight, and left until you hit a
wall, and go right, into another opening we just opened. Now open the Yellow
Door, and get the Red Key. Now return to the pillars, and hit the south switch
on the right pillar. Now go right, take a left, and then right into this
opening. Open the Red Door in this room.

Go left, until you hit a wall. Turn to your right and kill the Lost Soul. Check
the wall he was guarding, and it should open. Grab the Radiation Suit, turn
around, run straight through the lava pit, grabbing the health if you need to.
Then, run into the pit. Open the door down here. Follow the hall to the exit
door, and then go through the exit teleporter.

———————–
E3M5: Unholy Cathedral
———————–

At the start, you can see 2 openings. Take the one on the left, and open the
door inside. Go in, and grab the Shotgun Shells to your right. Then turn
around, and follow the hallway to 2 doors. One of them leads to 4 teleporters.
Go through that door, and walk on the teleporter. When you get warped to a new
place, a door will open, and the room has power-ups, and a Demon or Baron
(depending on the skill level). Go in the room the enemy came out of, and grab
the goodies (this will add to your secret percentage). In each corner of this
room is a teleporter. Take the teleporter in the northwestern part of this room
(use your Automap for to find the exact teleporter).

In this new room, kill all the enemies here. Heal yourself with the Medikits in
here too. Also in this room are 2 doors next to each other. Take the one on the
right. Go into the room, and follow the hallway to a red pillar. Walk through
it from the south end, and then the wall in front of you will lower. Go into
this room. In this room, there’s a crushing pillar in each corner of the room
with a switch behind it. Hit the switch under the northeast pillar, and then in
the northwest part of the room, a platform will lower, containing the Blue Key.
Now, behind the southwest pillar in this room is a teleporter. Go through it
(the pillar locations are from the entrance of the room).

Now, we’re in this familiar room again. This time take the left door. Follow
this hallway to the Blue Door, killing any Imps or Lost Souls in your way. Go
through the Blue Door, go left, open the exit door, and go through the exit
teleporter.

—————–
E3M6: Mt. Erebus
—————–

You need to be quick with my instructions on this level. At the start, go left,
and cross the lava pit, and stop when you get top another platform. From where
you are, look around for a staircase. Climb it, and when you get to the top,
jump off to the floor in front of you. Kill the enemies here, and on this
platform, collect the weapons, and the Invincibility Sphere. Once you collect
the Invincibility Sphere, face the small platform where you got the weapons,
and *run* right, onto another platform. On here, *run* to the wall with skull
heads on it. From the wall, go left, then right, and jump into the pit. Now
*run* straight, heading towards the teleporter in the small alcove. When you do
teleport, open the door in front of you. You may pick up the Blue Key on easy
skill levels, but it’s not needed for these instructions.

In this room, you NEED to be invincible, otherwise you can’t do the next part
safely. From the door, check all the walls to the left until one opens (the
secret wall has a tiny candle in front of it). Inside the secret alcove, go
through the teleporter. When you get teleported you here, turn around, and when
you do, go *slowly* right onto a smaller ledge. Facing the wall, to the right
on the smaller ledge, switch to your Automap and make your you (the arrow) has
its back to the Blue Box. If you are, read this next sentence: YOU MUST STILL
BE INVINCIBLE!

Then, when your back is to the Blue Box, take out the Rocket Launcher, save
your game (if you are invincible). If you are playing on Skill Level 1, hold
Shift. Fire. Right when you fire, hold down. If you do make it to the box, jump
in. On Skill Levels 2 and up, you don’t need to hold Down or Shift. Getting
here Invincible and making it in the box takes a lot of practice, so keep
trying to get in the box. When you are in the box, hit the exit switch (this
took you to the secret exit ;-)).

————–
E3M9: Warrens
————–

Hey, this level is a replica of E3M1! How cheap! Anyway, hit the switch in
front of you. When the platform lowers, head straight to the door and hit the
switch to the left of it. The door will open. Go through the opening to the
right, and open the door. In this room, open the door to the right. Now, open
the door at the end of this hallway. In this room, open the door across from
us, and kill the Imps inside. The secret to the left of the exit door is still
here. Open the secret wall and get the stuff. Now go through the exit door and
step on the exit teleporter. Hey! The wall in front of us is lowering! Get to
the other end of the room, grab the Blue Key, avoiding the Cyberdemon in here
(you don’t need to kill it, don’t bother). If you can, grab all the new goodies
in here, and when you are done, backtrack to the starting room, avoiding any
new appearing enemies.

In the starting room is a new alcove. Take out your BFG, and go through the
alcove. Sooner or later, you’ll teleport. When you do, take that BFG and kill
the Cacodemons in front of you. If you have enough ammo, use it to kill the
Shotgun Guys that will ambush you from both the right and left. From where
the Cacodemons were, go left and grab the Red Key. Turn around, go straight,
and when you get to where the Cacodemons were, go left, and exit this room back
into the starting room. Go to the door, hit the right switch (it is a Red Door,
and you may need to hit it a couple of times), and go inside, through the exit
teleporter.

————
E3M7: Limbo
————

At the start, go straight, into a bigger room. On the western part of the room
is an opening. Go through it. Then, go left, and right. Follow this hallway to
a blood pit. Pass it. After you pass the blood pit, there will be an alcove to
your right. Go in and hit the switch. Turn back around and head right, and then
get the Blue Key. Kill any Demons that come towards you. Now, backtrack your
way out of this maze, to the big “O” room. Cross this room (or take the
platform to get around safely), and go in the opening across from the one we
just came out of (avoid any new enemies). In this room, there are 2 Blue Doors.
Take the one on the left. Go through it (pick up the Shotgun Shells next to the
Blue Doors).

Cross the bridge in front of us, and still head straight. Jump into the small
pit, and go straight. Kill the Cacodemon in here, and pick up a Radiation Suit.
From the alcove we just came out of, take the opening on the left. In this
small hall, go straight, getting into another room. Kill the Shotgun Guy, and
go straight into another opening. Now, follow this hall to another opening.
Follow it to a teleporter. DO NOT GO THROUGH IT. Before it is an opening on the
left wall. Go through it, and at the end of the opening, turn left into another
platform. Kill the Shotgun Guy on this one, collect the Cell Ammo, and pick up
the Red Key. Open the Red Door in here, and flip the switch. Now turn around,
go straight, and then right. Now go through the teleporter.

You will be right near where the Blue Key was. Get out of here again back
Into the large “O” room. This time, go through the opening to the left. To the
Left and right of you, there are 2 pillars. On the northern part on both are
small openings that lead to a teleporter (each pillar I tell you to go to will
have a small opening leading to a teleporter). Get to the pillar on the left,
and take the teleporter. On this platform, hit the switch. Now, take the
teleporter back, and go through the teleporter on the eastern part of this
room. When you do teleport, get the Yellow Key across from you, and take the
teleporter back. Before leaving this room, get on the platform to the left of
the opening, and kill the Demon. Grab the health and a Radiation on this
platform, and now exit this room. Now go right, and through the opening. This
time, go to the large blood pit we passed on the way to the Blue Key. Get to
the pillar in this pit, and go through the teleporter inside. When you get to
this room, go straight, and turn right and hit the switch. Get out of this
room, and back in this huge blood pit, get out of here and go to the “O” room
again. Get to the middle, and go through the teleporter inside the pillar.

In here, go straight. Open the Yellow Door, collect the Health, and hit the
switch. Return to the teleporter. When you get to the “O” room again, go right,
into here again. Instead of going left this time, go right, take another right,
and then left, into the blood pit. In the blood pit, take the teleporter inside
the pillar. In this room, open the Yellow Door, cross the bridge, open the exit
door, and go through the exit teleporter.

E3M8: Dis
———-

Congratulations, you’ve made it to the final level of episode 3! Anyway, open
the door in front of you. Go straight, and get out of the opening. Go right and
kill and kill The Spider Mastermind. Here are some tips:

1. If you have a BFG with at least 120 cells, you can use that to kill her. It
will only take 2-3 blasts.
2. On any skill level, you can have the enemies attack the Spider Mastermind to
weaken her.
3. In the center of the room, open the door. Inside is some Armor and a Plasma
Gun.
4. You can stay in the center room, and take potshots at the Spider Mastermind
every now and then.
5. Also, on the platform surrounding the level there are Rockets and Cell Packs
if you need them. To get them, use the staircase in the east part of the room.

Once you defeat the Spider Mastermind, congratulations!

Once the Spider Mastermind is dead, you get a little story:
——————————————————————————-
The Loathsome Spiderdemon that masterminded the moon bases and caused so much
death has had it ass kicked for all time. A hidden doorway opens and you enter.
You’ve proven too tough for Hell to contain, and now Hell at last plays fair –
for you emerge from the door to see the green fields of Earth! Home at last.
You wonder what’s been happening on Earth while you were battling evil
unleashed. It’s good that no Hell-spawn could have come through that door with
you…
——————————————————————————-
 
After the story comes the “ending”. Once the ending is over, press Escape, New
Game, then select Thy Flesh Consumed as the episode. Then, select the skill
level, and you start episode 4.

<><><><><><><><><><><><><><><><>
Episode 4: Thy Flesh Consumed
<><><><><><><><><><><><><><><><>

Episode 4: Thy Flesh Consumed, is only found in “The Ultimate Doom”. If you
don’t have “The Ultimate Doom” and only have “Doom”, then you do not have this
episode (you go as far as the end of episode 3). So don’t read this episode if
you don’t have The Ultimate Doom.
There are patches to upgrade your Doom to The Ultimate Doom at
www.doomworld.com, however. First, before you upgrade to Ultimate Doom, first
upgrade your current Doom version to 1.9 (unless it’s 1.9), and then upgrade to
The Ultimate Doom.

E4M2: Perfect Hatred  
———————

Kill the 2 Shotgun Guys in front of you at the start. Collect the health on
this platform too. From where you started, kill all the Imps, Demons, and
Cacodemons heading your way. Also from where you started, there are 2 sets of
stairs in front of. *Run* through the one on the left to make sure you land on
this platform. On this platform is a switch. Flip it. Turn around to see a new
opening. *Run* to get to it.

In here, kill the Imps and Shotgun Guys near you. Jump into the pit and grab
the Radiation Suit down here. Before you hit the switch, turn left. See that
“triangle”? Here’s a map if you don’t know what I’m talking about:

     /      
    /   _____

                             
/
The _____ is the switch. The /   is the triangle (you can see it in the
Automap). Walk up to the triangular wall and you’ll here a door open. Now, get
to the switch. Before you hit the switch, save your game. Now, hit the switch.
When you hit the switch, turn right and *RUN* to the rising platform. Follow it
to the platform we didn’t go to yet, and *run* again, to get across the small
gap. Pick up the Plasma Gun, and a hidden door will open, containing a Baron of
Hell, an Energy Cell Pack, and the Yellow Key. Kill that Baron with your new
Plasma Gun, and get the Yellow Key. Now drop back in the pit again, and go
through the opening. Go straight, heading to a teleporter. Go through it.

You’re back at the starting room again. This time, *run* through the staircase
to the right. When you land on this platform, hit the switch in between the
yellow bars (the Yellow Key is needed). When you hit it, turn to the right and
kill the Lost Souls that just appeared. When they’re gone, *run* to the
platform they were on. Get the Armor and Rocket Launcher, and then on this
platform, there’s part of the platform in front of an opening. Once again,
*run* to get to it. Jump in the pit below, and kill any Cacodemons and Spectres
down here. If you want to save ammo, there’s a Chainsaw you can get down here.
When everyone is killed down here, explore this room for another opening that
has a staircase. When you do find it, climb the stairs to a teleporter, but
don’t go through it yet. To the left of it is an opening. Inside is another
Baron and a Blue Key. Take down the Baron, and get the Blue Key. Now go through
the teleporter.

You’ll be at the starting room again. *Run* through the staircase at the left
again. *Run* straight again, crossing to get to another platform. See that blue
pillar? First, blow up the Barrel in front in of it, at a safe distance too.
Then, open up the blue pillar (same thing as a Blue Door), and climb up the
stairs. Behind a lump is a Cyberdemon. Ignore it (don’t shoot it, and walk up
to the door, and it will open by itself. Kill the Cacodemons in front of you.
Then turn around, go back down the stairs. At the bottom of the stairs, go
left, and take the teleporter. Save your game before you enter the teleporter.  
You will be where the Cyberdemon is. You should telefrag him, and he should be
killed like that. Get the BFG here, and lower the lump. When it lowers, go
right, *RUNNING* into the pit, following the right wall (be quick). If you were
quick enough, you’ll get to this opening. Go inside, and hit the exit switch
(this took you to the secret exit ;)).

———–
E4M9: Fear
———–

At the start, open the door in front of you. Collect the Shotgun in here, and
open the other door in here too. Kill the Zombiemen in front of you, and from
the door, hit the switches to the right and the left. When you do, turn back
around, go through the doors again. When you get out of the second door, go
straight, and when you get into a hallway, go right. When you get to a door
(not the one to the left wall), turn right and face the gap to your right. See
those pillars to the right that have openings in between them? Use this map:
          __

|        |  |  
|     |_  _  _  _  _   _   _  _   _  
|        
|        X
|________________________________________________

Say the X is you. The Y is the Yellow Key. The spaces between the | and _ are
openings you can run through. Now, see that opening in front of the pathway?
Now, back up, and go through the opening and you’ll be on the pathway. Cross it
to the Yellow Key. Now, drop down to the pit below you. Down here, step on the
teleporter next to you.

On hard skill levels, you may telefrag a Baron when you get here. In this
little “cage”, flip the switch on the pedestal. Then, go right, then run to the
door. Then, in here, take the staircase on the right, and kill the Shotgun Guy
at the top, and then open the door. Kill the Imps and Shotgun Guys in here.
From the door, go straight and take the lift down. When you get to the bottom,

to a door on the left wall. Open it. Go through. Follow this hallway to a
Yellow Door, killing any Demons, Imps, Zombiemen, or Cacodemons in your way.
Open the Yellow Door, and get to the exit switch (don’t flip it). Facing the
exit switch, turn around, and check the walls. When part of the wall opens, get
the Backpack inside. Now go back and hit the exit switch.

E4M3: Sever the Wicked
———————–

Collect the Shotgun Shells and Shotgun in front of you, and run straight into
A pit. Kill any enemies down here. Now, go down the staircase, and kill any
Imps and Shotgun Guys down here. From the bottom of the staircase, go left,
where you see 2 staircases (one goes up and one goes down). Head upstairs, and
follow this hallway to a door. As you approach the door, a hidden door behind
you will open. Kill the Imps inside, and grab all the goodies in here,
everything you can get (this adds to your secret %). Then turn around and open
the door. Kill any enemies in here, including that Baron on hard skill levels.
When everyone here is dead, drop in the pit. Down here, get to the normal
floor, not this harmful lava. On the floor we’re on is a pedestal with a switch
on it.

Hit it. The platform in front of you will lower, containing the Red Key. Grab
it, and turn around. Kill any enemies down here, and down here, follow the
right hand wall to an opening. When you get to it go through. In here grab the

face the wall behind you. Open it like a door in go through. In here head up
the stairs in front of you. At the top grab the Shotgun Shells, Rockets, and
the Soulsphere, head back down the stairs, and leave this place. Back in here,
take either path to the teleporter (left or right), grabbing the Boxes of
Rockets. Take the teleporter.

When you teleport, kill the Spectre in front of you. Then, check the wall
across the teleporter. It will lower. Run straight, outrunning these enemies.
Over here, you have 3 paths to take. Take the one on the left. When you get to
the wall, go left, and take another left, up the set of stairs. Kill any new
appearing enemies here. From the set of stairs, go straight, and then turn
right, up a staircase. Up here, head straight to get to a lift, leading up to
where we started. When you get to the top, go left, and take a right into an
“outdoor hall”. In this hall, open the Red Bars, and kill any enemies here,
including that annoying Baron. From where the Red Bars are, Go straight,
towards that pillar in front of you. Behind the pillar is the Blue Key. Grab
it. Now turn back around, exit this room, into the platform where you started
this level. On this platform, go all the way left (don’t fall off), towards the
Invincibility Sphere. Grab it, and fall off this platform to the left. Then,
fall off again, into the blood pit. Down here, open the Red Door. Go inside.

From the Red Door, go left, and take the spiral stairs to the top. At the top,
take a right, getting to a staircase. Take the staircase to the Blue Door. Open
it. Go through it, and kill any enemies inside here. Follow this hallway to the
exit teleporter.

Open the door in front of you. Collect the Shotgun and Shotgun Shells in here,
and kill the Spectres and Imps in here. When you do, take the lift across from
the door we took. When you get to the top, open the door in front of you. Go
straight, and jump into the pit on the northeast part of the room. After you
get in, go left (from the door), and take the lift up back up here. Now, go

———————–
E4M5: They Will Repent
———————–

At the start, go left, and take another left going downstairs, killing any
enemies in your way. When you get to the bottom, go straight, and open the
door. Go right, and when you get to an opening to the right, go in and open the
door. In here, go straight, activate the lift, killing any Imps or Lost Souls
in your way. When you get to the top, take a right and get the Red Key, and
kill any Zombiemen and Shotgun Guys up here too. Now, drop back down to the
floor below you. Down here, head right to the door. Open it and go through. In
here, walk straight until a wall on you lowers. Down here, go right until you
get to a gap. Once you get to it, drop in it. Down here, head left and grab the
Radiation Suit. Now head up the stairs to the right.

*******************************************************************************
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!IMPORTANT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Right here is one of the most biggest shortcuts in the game. I recommend doing
it, as it’s really easy and skips you from most of the hard parts. If you wanna
take it, read on. If not, skip all the walkthrough that’s in the *s and keep
reading.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!IMPORTANT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
At the top of the stairs, turn right. Now, follow the left hand wall until you
see an opening to the left of the pathway. Once you see it, drop down it. Down
here, get the Soulsphere and follow the left hand wall to a gap. Once you get
to a gap, cross it. On this platform, cross the gap in front of you. You’ll be
in the room with a Yellow Door. See the window to the left of it? Back up, and
*Run* through the window. You’ll be in the exit room. In here, hit the exit
switch (note that you skipped the Yellow Door as well!).
*******************************************************************************

At the top of the stairs, turn left. Open the door in front of you, and go
through. In here, follow this hall to a Blue Key. Once you get to it, the floor
you’re on will lower. Now wait for it to rise back up again, and when it does,
turn around and leave this room. Back in here, follow this path to a Blue Door,
killing any Zombiemen, Shotgun Guys, or Barons of Hell in your way. Once you
get to the Blue Door, open it, and go through.

In here, kill all the enemies on the platforms. Now, cross the platforms to an
opening. In here, walk straight and the floor you’re on will lower. Down here,
you’ll be in the room with the Yellow Key. You have two options:
                 
1. Use a trick to get past the Yellow Door without the Yellow Key and get to
the exit.
2. Get the Yellow Key to open the Yellow Door and get to the exit.

???????????????????????????????????????????????????????????????????????????????
If you chose number 1, position yourself in front of the window. Now back up,
and *RUN* straight, running through the window. You’ll be in the exit room. Hit
the exit switch.
???????????????????????????????????????????????????????????????????????????????

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>

If you chose number 2, head down the stairs and get in front of the Yellow
Door. Now, head left. See that switch on the wall? Hit it, and it will open
like a door, so go through. In here, check the wall to your left and a hidden
door should open, revealing a Berserk. Grab it, and head through the teleporter
to your right. In here, cross the pathway to the Yellow Key. Now, turn around
and drop down to the pit in front of you. Down here, take the teleporter in
front of you. Now, when you teleport, open the door in front of you (which is
the switch on the wall). In here, follow the left hand wall to the Yellow Door.
Once you get to it, open it, and go through. In here, hit the exit switch.

E4M6: Against Thee Wickedly
—————————-

Grab the Shotgun Shells in front of you, and kill the Shotgun Guy in front of
you. Now work your way out of here into a larger room, killing any Imps, Lost
Souls, or Shotgun Guys in your way. When you do get into a larger room, you
will see a platform having the Blue Key on it (you can’t get it). Kill any
enemies in here too. Facing the Blue Key, drop down into the pit in front of
it, and go left getting to an opening. Go through it, and as you go, you’ll see
a floor with ammo and a Radiation Suit on it. Get the Radiation Suit, get into
the blood river again going left. You will need to drop into the pit, but
before you do, you’ll see a pillar with a teleporter on top, accessed from 4
different lifts around it (depending on which lift you take, it will teleport
you to a different area). From our view, here’s what we see:
          N
          __
       W |__| E
          S
———————
          X
Say the X is you. Take the “S” lift to get to the teleporter. When you do
teleport, grab the Chaingun in front of you, and run to get to the platform
across from this one. Kill the Shotgun Guy and Spectres in front of you, and
then go straight, heading up a set of stairs. Up here, grab the Health and the
Blue Key. Then go back down the stairs, go straight, and get into the blood
river again. Go left, get on the platform where we got the Radiation Suit, and
check the walls until a hidden door opens. Go inside, go straight, get past the
first set of stairs, but go up the staircase after it. Check the brown wall in
front of you, and it should open. Go inside, grab the Rocket Launcher, and kill
the Baron (don’t use that Rocket Launcher, or risk committing suicide). From
where we entered, hit the switch on the right wall. Then take a left and open
the door (it has a demon face on it).

Kill the Imps and Shotgun Guys in front of you, and go straight, and then hit
the switch in between the Blue Bars. Turn around, and climb the stairs to the
right to get the Yellow Key, killing that Baron on Hard Skill levels. Turn back
around, and before you go into the pit again, here:
         N
       |—|
     W |   | E
       |—|
         S
———————
       X
The X is you again. Drop down, and use lift W to take the teleporter. When you
do teleport, go straight, follow this bridge to another room. In here, kill the
Imps, Spectres, and Shotgun Guys.. See that pole in between the Red and Yellow
bars? Walk around it to reveal a teleporter near the Red bars. Go through it.
You will telefrag a Shotgun Guy. Drop into the blood pit, kill any Cacodemons
here, and grab the Radiation Suit if you need to. Down here, open the Yellow
Door, kill the Imp, get the health, and hit the switch. Exit this room, go
right, and take the teleporter. Now that the Yellow bars have been removed,
run across the gap the get to the teleporter the bars were in front of. Take
it.

Go straight, and follow this hallway to the Red Key, killing any enemies in
your way. Now turn back around, and exit this hallway. To the left a wall has
lowered, with a Cyberdemon behind it. Kill it (you need to, otherwise you can’t
beat this level), using your Rocket Launcher and BFG. When you do kill it,
*run* up a small ladder on this balcony, and cross the bridge to get to this
room again (this room had the Yellow and Red Bars). Get back in the blood pit,
and open the Red Door. Kill the Imp and Cacodemon in here, and hit the switch.
Now get back out of this room and go left, taking the teleporter. Now with the
Red Bars removed, get to the farthest to the right where the Red Bars were, and
look right. You’ll see a platform with goodies and a teleporter at the end.
*Run* to get to the platform, get the goodies, and take the teleporter.

When you teleport, you’ll be on the platform where the Cyberdemon was. If he’s
alive still, kill him. If not, take a left, get up the stairs, get to the room
past this one, and take the exit teleporter at the northeast part of this room.

————————
E4M7: And Hell Followed
————————

Get the Shotgun, and kill the Zomebiemen and Shotgun Guys in front of you. Then
go straight, and when you see 2 staircases to the left and right, take the one
on the left. When you get to the top, go left, and kill the Zombieman in front
of you. Then, get to the switch that the Zombieman was in front of, and hit it.
The wall in front of you should lower. Go inside, and take the staircase on the
right. At the top, go left, and get the Red Key on the platform, killing any
Lost Souls or Cacodemons in your way. Exit this room from where you came from
now.

Just before the staircase in front of you is a staircase to the right. Go down
it again, and at the bottom, turn left, and open the door. In here, jump into
the pit across from you, killing the Shotgun Guys in your way. In the pit, go
left. Follow this hall to a floor with a Radiation Suit on it (kill the enemies
in your way). From the Radiation Suit, turn left, and open up the Red Bars.
From the Red Bars, go straight, and take the lift on the left. Kill the Shotgun
Guy on it. Get to the top using this lift.

At the top, go straight, and hit the switch (watch out for the Baron up here on
hard skill levels). The wall in front of you will lower, revealing another
Baron and a switch. Kill or avoid the Baron, and hit the switch. From the
switch, go straight, and fall onto the ground below you. From here, go
straight and then left, crossing this new bridge. On the platform it leads to,
get on the flashing square, and then a lump should raise with a switch on it
(this is the exit switch). Hit this switch, and you’re done with this level!

———————
E4M8: Unto the Cruel
———————

Congratulations, you’ve made it to the final level of Episode 4, and this game!
Anyway, get the Shotgun in front of you, and kill the Imps around you. Then go
down the stairs, and flip the switch down here, and the door to the left will
open. Kill all the Zombiemen, Shotgun Guys, and Spectres in here (or let them
fight). From the door we entered, go right, and follow this hall to a wall with
a Demon head. Check it. It should open, revealing the Red Key. Turn back around
to the door we entered to get here, and cross the bridge to get to this
platform. On here, open the Red Bars, and kill the Baron. Also in this small
room is a switch. Flip it. Now leave this platform and go back to the door we
used to get here. Follow the other hallway to a Demon head. Check it. Go in,
and take the teleporter.

Kill the Imps and Shotgun Guys in here. From the teleporter, go straight, and
head up the staircase. At the top, go left, and follow this bridge to another
platform. Kill the Baron on here that appears on hard skill levels, and get the
Armor. In here, go down the stairs, and follow this bridge into another room.
Kill the enemies in here, and hit the switch in here. When you do hit it, take
the lift down to the left.

Down here, follow this hall to the Yellow Key, killing any enemies in your way
(watch out for 2 Barons on hard skill levels). When you get the Yellow Key,
turn around, go straight, and hit the switch to the left. Ride this lift up
again, and up here, backtrack your steps to the teleporter we used to get here.

In here, open up the Demon face door. Now cross the bridge to the center
platform again, and this time open the Yellow Bars. Kill the Baron in here, and
hit the switch in this small room. Now, instead of crossing the bridge we used
to get here, cross the new bridge on this platform. Climb the stairs, and open
the door.

In here, walk around the pillar to get to the Spider Mastermind. Kill it. Here
are some tips.

1. Use your Rocket Launcher or BFG to kill her. It only takes 2-3 BFG hits to
kill her.
2. On hard skill levels, there will be a few Barons in here too. You can use
them to weaken/kill the Spider Mastermind.
3. Near the Spider Mastermind is a hidden area with a BFG and some ammo. Check
the walls while she’s in a fight with an enemy so you don’t risk being killed.

When you do kill the Spider Mastermind, the pillar we walked around will lower,
revealing the exit teleporter. Take it, and you’ve finished the game!
Congratulations on defeating her!

Once you step on the exit teleporter, you get a little story.

——————————————————————————-
The Spider Mastermind must have sent forth its legions of Hellspawn before your
final confrontation with that terrible beast from Hell. But you stepped forward
and brought forth eternal damnation and suffering upon the horde as a true hero
would in the face of something so evil. Besides, someone was gonna pay for what
happened to Daisy, your pet rabbit. But now, you see spread before you more
potential pain and gibbitude as a nation of Demons run amok in our cities. Next
stop, Hell on Earth!
——————————————————————————-

A few seconds after the story is done, you can see a screen of what happened
after the ending from Episode 3.

^_^ Woo-Hoo! I’m done guiding all 36 levels! ^_^

============
11. Secrets
============
Now I’ve decided to add a secrets section, which will really make my Ultimate
Doom Walkthrough Ultimate. This will cover every secret in the game. You can
use my Walkthrough for parts of this section too.

************************
E1M1: Hangar: 4 Secrets
************************

1. In the room with a zig-zag floor, walk up to the door, but check the walls
to the right of it. One should open, so go through. In here get the health and
ammo, then follow this hall to an opening, and go through. Out here, get the
MegaArmor in the middle of the room.

2. Now go back and open the door, and in here, get to the exit door. Then turn
around an go back to the room with the zig zag floor. Remember the platform
with the Imp on it? It has lowered. Go inside and get the Medikit, Shotgun, and
Shotgun Shells.

3. From Secret 2, get back to the Zig-Zag room. See the light posts at the
north part of this room? Get to them. Now, turn around and face the opening
that lead to Secret 2. Facing the opening, and with your back in between the
light posts, back up. You should then see a wall lower in the Secret 2 room.
*RUN* to the lowered wall, get on it, and ride it to the top. Up here is a
hallway of Armor Bonuses and a Box of Shotgun Shells, and an opening back to
the zig zag room.

If the wall/lift raises before you get to it, get back to the light posts, back
up a little bit, and the wall/lift will lower again (there is a trapwire you
must step on that’s between the opening in the light posts).

Note: At the start, go to the room to the left. Between the staircase are
pillars. On the east part on the right one is a switch. Flip it. Get back into
the starting room, and to the right of the windows is a new opening. Go through
it, and you’ll be in the room with the MegaArmor. This can cut through the
whole level almost. This is an Ultimate Doom Only Secret (this “secret” does
not affect your secret %).

********************************
E1M2: Nuclear Plant: 6 Secrets
********************************

1. At the start, take a right, and then left. See the walls to your left?
Check them until a hidden door opens. Go inside and get the goodies in here.

2. In the previous secret room, hit the switch in there. Then get out of that
room, and there is a door to your right and left. Take the one on your left.
Climb up the first set of stairs, and you’ll see an opening next to you. Out
here has a Chaingun, Box of Bullets, and a Soulsphere.

3. When you have the Red Key, go through the Red Door, and go in the room to
your right. Hit the switch on the pillar in here, and leave this room. Across
from you is an opening to a maze. Go inside. In the southeastern part of this
maze is part of a wall in between 2 poles. Check it, and it should open,
revealing a Backpack.

the stairs. When you get to the top, get to the other end of the room. When you
get to the wall, turn around. You should see a gray platform. Getting on it
triggers a secret room. Here’s how to get on it:

                                   
|
         
|    X   
|              
|  <– Blue Door
         
|———|              
|
       |–|_________|–|            |
      
|_______________|                
 

Say the X is you. Get on the small ledge, and walk forward. A wall in front of
you should open. Kill any enemies that appear, and grab the goodies behind the
wall that just opened (the ledge is the — part, and you walk up to the ___
part that’s shorter, and the other ___ part is another ledge).

When this happens, a hidden door in front of you should open. Get to it, and go
in the new room. In here is a secret, and some goodies.

6. Get out of the secret 5 room, and go right. You’ll see an opening to the
right. Facing the opening, walk up to the wall to the left of the opening. The
wall should lower. When it’s finished lowering, you’ll be able to access
another small room. Getting in it counts as a secret (get the goodies too).

13. Tricks
===========

———————————
Exit E1M9: Military Base Quicker
———————————

In E1M9: Military Base, use my Walkthrough to get to the Blue Key. When you get
the Blue Key get to the Blue Door, open it, and go through. In here, you can
strafe run to get on the platform in front of you without having to hit a
switch to rise the pathway. If you can strafe run across the gap and onto the
platform, you can hit the exit switch, and you won’t need to go in the slime
river and hit a switch.

———————————
Bypass the entire level in E2M2:
———————————

At the start, go straight. When you have the chance to go right or left, go
right. Over here, go straight until you hit a wall. When you hit the wall, go
all the way left to a crate. Walk up to it, and it should lower. Now go
straight, through the opening across from you.

In this room, turn right, and through the opening. Follow this slime river to a
wall (run). When you hit the wall, turn around, and get to the wall to your
left. Hugging the wall (turn right and left, and check different parts of the
walls too), keep pressing the spacebar until you hear the sound effect of a
switch. Now *run* right and get to the bridge rising (if you don’t, you’ll be
killed). Now open the exit door, and hit the exit switch.

———————————————-
Pillars with switches lowered into the floor?
———————————————-

In some levels (let’s use E2M2 as an example), there are pillars with switches
that lower into the ground, and the switches are no longer visible on the
screen. But you will still be able to activate the switch. Just get in front of
the side of the pillar where the switch is and face the switch. Now press the
Spacebar and it will be activated (just get in front of where the switch was
and press the Spacebar like any other switch).

The pillars I’m talking about in E2M2 are the 3 in the Yellow Door room. Just
hit one switch and go into the room the switch opened. The other two pillars
will lower.

—————————
Bypass much of E3M7: Limbo
—————————

In E3M7: Limbo, use my Walkthrough to get to the Red Key, then get to the big
“O” room, and go through the opening in the north part of this room. In here,
instead of taking the teleporter in the opening in the left, take the one in
the right. When you teleport, you’ll notice there isn’t a pathway in front of
you to get to the Yellow Key. But you can do a *Strafe-Run* (running at an
angle strafing) to get to the Yellow Key, crossing the gap in front of you.
Once you have the Yellow Key, get back to the Big “O” room. Back in here, take
the teleporter in the middle of the room. In here, there’s no pathway to the
Yellow Door, but you can Strafe-Run to run across the platform to get to it.
Once you get to the Yellow Door, open it, and go through. Hit the switch in
here. Now get to the exit.

Strafe Running across the platforms does take a while to get it right, but if
you’re good at this, you can get through this level saving lots of time, and
not needing to hit two switches in this level.

———————————-
Get to E3M9: Warrens much quicker
———————————-

Ok, to do this, use my Walkthrough or E3M6 to get to the blue box that has a
switch inside to get to the secret exit (E3M9). Now, instead of having a Rocket
explosion throw you back into the box, you can activate the secret exit switch
outside of the blue box. Here’s what to do: Drop down to the blue box, and get
on the left or the right side of the box. Now, facing the north end of the box,
get on an angle to the north end of it (use the Automap to get in front of the
secret exit switch outside the box), and once you’re at an angle facing the
north end of the box (and being just in front of the switch as if you were in
the box, press the Spacebar until you get to switch activated (this will take
several times, but if it won’t work, position yourself a bit more to the
switch).

———————————
Bypass the entire level in E4M2:
———————————

At the start, use my Walkthrough to get to the first teleporter in the level.
Don’t go through the teleporter. Facing the teleporter, check the walls to the
left until a hidden door opens. In here, get the Berserk and go right to the
Energy Cell Pack. When you pick it up, check the walls to the right of it and
a hidden door should open. Follow this hall to the other side of the
teleporter. Now take the teleporter.

You’ll be teleported to a different place this time. Save your game. Walk and
pick up the MegaArmor, and turn around. At an angle, hold Shift, Alt, and *run*
right off this platform, hoping you land on the stairs past the Blue Pillar. If
you don’t do it, load up your saved game again, and try it again. When you get
on the stairs, follow it up to the door, and when it opens, turn around and try
to get on the platform before the Blue Pillar. Now take the new teleporter
here, and use my Walkthrough to get to the secret exit.

——————————–
Bypass the Yellow Door in E4M5:
——————————–

Now use my Walkthrough to get to the Yellow Door. Standing right in front of
the Yellow Door, turn around and go up the stairs. Up here, turn around. You’ll
see a wall with an opening to the left of the Yellow Door. Now get back at a
fair distance (don’t fall in the gaps behind you), blow up the barrels in front
of you, get center with the opening, and *run* straight to the opening. There’s
a good chance you got through the opening, and bypassed the Yellow Door. From
here, you can hit the exit switch.

14. How to use a BFG9000
=========================

Don’t you hate it when you fire a BFG9000 and it doesn’t kill any enemies in
front of you? Well, here’s how to use it correctly. Here are the locations I
have found the BFG:

E3M3: Pandemonium
E3M4: House of Pain
E3M5: Unholy Cathedral
E3M9: Warrens
E4M2: Perfect Hatred
E4M5: They Will Repent
E4M6: Against Thee Wickedly
E4M7: And Hell Followed
E4M8: Unto the Cruel

The BFG9000 should only be used carefully. It will also kill any enemies that
you see once the BFG blast hits something.

                 ___
—————-| X |—————
  S

S            
E

E

|
        
E     E  B

———————————–

The X is you. The B is where the BFG blast hit. The E are the enemies that die.
The S are the ones that survive. If you turn right and back up (so you can see
the BFG blast before it hits something), it should also kill the enemies that
were the survivors.

********************
How to dodge a BFG
********************

If you play a Doom online deathmatch, you should be aware of people who use the
BFG frequently. They shouldn’t be too much of a problem if you know how to
dodge a BFG blast correctly. If you know how to, look here.

 _________________________
|                    
_   |
|  M                B|_|X |
|                        
|
|                        
|
|_________________________|

Say the X is you. The M is your enemy and the B is where the BFG hit. The
square between you and the BFG blast is a pillar. Since your enemy couldn’t see
you and the BFG blast hit, you will not be hurt/killed. If you move out and he
can see you, you should be killed.

As long as your enemy cannot see you, the blast is not going to hurt/kill you.
Another way to do this is not only hide behind something, but to get out of
your enemy’s sight. Since it takes a second or two before the BFG fires, you
can also try to kill your enemy and then hide when the BFG blast is launched
(even if an enemy is dead the BFG can still kill you).

15. Bugs and Errors
====================
Here are some known bugs and errors I found in the game. If I forgot any, tell
me!

1. In E4M3: Sever the Wicked, the maximum secret % score is 100. This is due to
1 secret found alone, and 19 found on a staircase. The other 2 secrets are on a
pair of torches near the secret stairs, and the player cannot step into the
torches.

2. In E4M7: And Hell Followed, the maximum secret % score is 50. This is due to
that the player cannot step into 2 of the secret areas without using any cheat,
only 2 secrets are accessible without cheats.

==========
16. Codes
==========

Here are some codes for all of you cheaters out there. Of course, you can use
these for fun in the game and to have fun in the levels. You can type these in
anytime during gameplay.

Permanent Invincibility: Press IDDQD to become permanently invincible. You
cannot be killed by anything, including slime pits, enemies, crushing ceilings,
and so on, until this is disabled in E1M8. You can turn this off at any time by
pressing IDDQD again. Another thing is this will set your health to 100%.

All weapons, full ammo, full armor, no keys. Press IDFA and it will give you
all of what I mentioned. Pressing IDFA again will max out everything again.

All weapons, full ammo, full armor, keys: Same as above, just press IDKFA and
you will get all of mentioned above.

Full Automap/Object Indicators: You must be in the Automap to do this. Press
IDDT and your map will be full. Press IDDT again and it will add object
indicators, which represent items, enemies, weapons, health, and so on.
Pressing IDDT after that sets your Automap to normal.

Find your current position and coordinates on map: Press IDMYPOS and you will
be able to see where you are on the map.

Gain power-up: Press IDBEHOLD and then one of these next letters will give you
a power-up:

——————————————————————————-
IDBEHOLDR: Radiation Suit (temporary)
IDBEHOLDS: Berserk (lasts for level)
IDBEHOLDA: Automap (no object indicators, unvisited areas are gray)
IDBEHOLDV: Invincibility (time limit, white screen)
IDBEHOLDI: Invisibility (time limit)
IDBEHOLDL: Light Amplification Visor (temporary)
——————————————————————————-

Warp to level. Press IDCLEVxx to warp to that level. For example, if you want
to get to E3M2, you would type in IDCLEV32. The first x is episode number,
second is level number. You can use this to get to secret levels.

Change level’s music: Press IDMUSxx to change the level’s music, and it will
switch the music to that level if you hate the music and want something better.
Just like level warping, IDMUS17 will change to the music from E1M7, where the
first x is episode number and the 2nd is level number.

Walk through walls: Press IDSPISPOPD and you will be able to walk through walls
and go as far off the map too. During this time you can still hit switches and
open doors but you will walk over most objects too. Just press that again and
it will be turned off.

Gain Chainsaw: Press IDCHOPPERS to get yourself a free Chainsaw. That’s all it
does.
