Doom 1

Submitted by: Dj Simo

#1 - From the start of the level: Enter one of the difficulty selection
slipgates. Walk towards episode 4. There will be a pool of water. Jump into
the pool and duck underneath the platform you were just standing on. Drop
through the water. You will land on a beam of wood. Walk along it and into
an archway (on your left, looking towards the entrance of episode 4). Walk
through the archway and through another slipgate to reach Nightmare mode.

E1M1 - The Slipgate Complex:

#1 - Forward and to the right of the start is a ledge with flashing lights.
Shoot the wall facing away from the start on that ledge (the wall has a red
design on it). There will be a box of shells behind it.

#2 - Underneath the first bridge you come to is a river. It flows into a
cavern. Enter this cavern and walk through it. As you pass by a set of
steps containing a 100 health item and a door to the end of the level
(which cannot be opened from this side), the game will register a secret.
At the end of the cavern is a lift taking you back up to the blue armor at
the start.

This secret can also be accessed at the end of the level. Climb up the ramp
to the room right before the slipgate out of the complex. Turn to the
right. There should be a column on the wall. Shoot the wall to the right of
the column. It will open the door which was previously closed, revealing
the river and 100 health box.

#3 - Past the first bridge is a door. Enter the door and kill the monsters.
To the right of the entrance is a column and a ledge. Go to the corner
between the ledge and the column. Shoot the globe texture high up on the
column. A platform will rise and you will be on the ledge. Turn to your
right and shoot the globe texture on the ledge. The wall behind the globe
will open, leading to a quad damage item.

This secret can also be accessed by the area right before the walkway over
the pool of slime. Before walking out onto the walkway, turn to your right.
There should be a red wall between two columns. Shoot it, allowing access
to the quad damage.

#4 - To the left of the door past the bridge is a large hall. Follow it to
the right. You will come to a large, shallow pool of slime. There will be a
button on the wall. Push the button and a platform will slide out from the
wall. Halfway across the platform, turn to your left. There will be a red
target in a depression slightly above your the level of your head. Shoot it
and turn to your left. A door in a wall will open, revealing a double
barreled shotgun.

#5 - Past the platform over the pool is a hall. Walk down the hall. You
will reach a walkway. Go down the walkway and turn left. Go down the
walkway again and turn left. There will be a button and a light in front of
you. Jump onto the bannister. Jump onto the light. Step onto the top of the
button. Look at the wall in front of you. There will be a ledge and two
blocks jutting out. Run and jump to the lowest block. Jump up to the next
block and to the ledge. Inside is a 100 health item.

#6 - Go all the way down the walkway. There will be a door. To the right
and behind a column will be a biosuit. Take it. Jump into the slime. Swim
underneath the door. Follow the tunnel to where it opens into a slightly
larger area. There will be a platform overhead. You won't be able to see it
unless you try to surface. There will be a boxed in area of the platform
that you can see, however. Swim up that opening. If you are running low on
air, you can swim up to the platform from the tunnel, but you must step
over the opening before the game registers the secret. There is yellow
armor and some health on the platform. There is also a slipgate to the area
over the door past the bridge (back near secret #3)

E1M2 - Castle of the Damned:

#1 - At the start, walk down the stairs and jump off to the right into the
water. There should be a green, lit wall in front of you. Shoot it and it
will open. Walk along the passage until you surface.

This secret can also be accessed by the area near the bridge with the big
red symbol over it (See secret #2). Jump off the bridge and swim underneath
it, going away from the symbol. You will swim under an arch and come into a
small room. There will be a ramp on the left. Walk up the ramp.

#2 - From the start, go forward until you reach the wall. Turn right.

E1M3 - The Necropolis:

#1 - From the start: Forward and to the left. Get the grenade launcher.
Turn to the left. There will be an ogre behind a set of bars and a couple
of other monsters. There will be two paths: one through the door to the
left and a set of steps leading down and to the right. Take the steps. Go
along the passage until you reach a bridge. Jump down. To the left of the
bridge and behind where you came from is an alcove. Shoot the back of the
alcove and the wall will open. There will be rockets and health inside.

#2 - Starting from the same bridge from which you jumped down in #1, cross
the bridge and turn right. There will be a short passage, two sets of
stairs, and a platform down. Go down and turn to face the left wall of the
passage you just went down. There will be a short corridor there. Go down
the corridor until you reach a shallow lake. To your left will be the gold
key. Take it. Turn slightly to the left. There will be an area of the wall
darker and with a slightly different texture from the rest. Go right up to
it. You will fall beneath the water. Ahead is a short passage. Swim through
it and up to land. There will be a ring of the shadows there.

#3 - From the area with the ogre behind bars (described in secret #1), take
the door. Get the nailgun and shoot the symbol. Go down the steps and
follow the passage. There will be a series of platforms. Go across the
platforms. You will reach a locked door. Open it (it uses the gold key
whose location is described in secret #2). Follow the passage. Jump down to
a set of tunnels filled with slime. Go forward, turn left, forward again,
left, take the first tunnel on the right, and up the ramp. Open the door.
Above you will be two ogres on platforms. To your right is a yellow armor
blocked by two sets of two bars each. Killing the ogres above removes the
bars. Shoot the wall behind the armor. The wall will open, revealing a
slipgate. Go through the slipgate. You will be on the platforms that the
ogres were standing on. There are rockets here.

slime with a bridge over it. Go to the end of the bridge and ride the
platform up. Step on all the touchplates. Two doors will open in the walls.
Enter both and press the buttons. The game should tell you that a secret
cave has opened. Jump onto the bridge and head back out to the deep pool
where you got the silver key. Along the right wall of the cave will be a
large, bright circular opening. Enter it. Swim up. Inside a little room is
a grenade launcher, health, and a slipgate to the secret level.

E1M5 - Gloom Keep:

from the wall. Run along the ledge and jump across to a platform with an
ogre. There are rockets and armor on the platform.

passageway until you reach a room where you are standing on a Y-shaped
platform. From there, take the right fork. Follow the passage and you will
come into a large room. Forward and to the left is a staircase. On the
right will be a square area with a column in the center. Walk up to the
column. Jump up and hit the torch with your head. Behind the column, a door
will open in the wall, revealing yellow armor and a touchplate to open the

hall, bars come down and block your exit, a wall opens, revealing several
ogres, and the spiked wall begins to come towards you. Kill the ogres and
escape using a lift that becomes unbarred with their death. Jump down onto
the stairs into the middle of the lava. These are the same stairs you just
went down. The bars will go up at some point and you will be able to enter.
This time when you enter, the bars will not go down, and if the spiked wall
has returned to it's original position, it will move as soon as you enter
(If it has not, simply go behind it and through the slipgate). Trigger the
wall and go back. Wait for the wall to pass and go behind it. There will be
a slipgate which leads to a super nailgun and a box of nails. You will also
