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.
Forward again. Turn left. There will be a bridge over a pool of water.
There will also be a large red symbol on an archway over the bridge. Go
onto the bridge. To the left, there will be a double barrelled shotgun.
Jump off and swim underneath the area of the gun. Swim under an arch and to
the right. Follow the passage. There will be a bridge above you all the
way. You will eventually reach a pool. As you enter the pool, the wall to
the left of you will open up. There will be 25 health, a box of nails, and
a slipgate to the ledge opposite the one containing the double barreled

#3 - Cross the bridge with the red symbol. Turn to the right and walk
through the door. Turn to the left. Climb the staircase. There will be a
column midway across the room on your right. Go to the side of the column
facing outward, towards the windows. A small plate of stone will be the
column. Push it. A door to the right will open to give you a quad damage

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.

E1M4 - The Grisly Grotto:

#1 - Through the door at the start there is a set of spiral stairs. On the
left and right at the top are two red symbols. Shoot them. The ceiling will
fall, revealing a yellow suit of armor.

#2 - From the bottom of the stairs, go through the passage. You will come
upon a deep lake. Get the biosuit. Dive into the water. Directly to your
right should be a small ledge where you can surface. Go up and you will get
a box of rockets.

#3 - From the pier with the silver key: Jump off and swim in the direction
of the pier. Surface on the other side. Go through the silver key door and
to the left. Follow the passage. You should reach a small body of blue
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:

#1 - Jump to the right and off the bridge you start on. There will be an
area sticking out of the wall, almost like a column. Beneath the water is
an opening to a ledge with a box of nails and 100 health.

#2 - Cross the bridge at the start and turn right. Follow the walkway and
pass through the gate. There should be a stairway down the passage. Jump
onto the bannister of the stairway. Jump across to a ledge that juts out
from the wall. Run along the ledge and jump across to a platform with an
ogre. There are rockets and armor on the platform.

#3 - Cross the bridge at the start and go through the gate. Walk along the
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
wall if it closes before you leave.

#4 - From the same large room described in secret #3, climb the staircase.
To the right is another set of stairs and an octogonal room with a slipgate
to the gold key. Go behind the slipgate and step or You will end up near
the start on top of the building you enter. There is a quad damage nearby.

wall will look turned --- it has roll added to it. Shoot the wall. It will
open, leading to a slipgate back to the gold key doors.

E1M6 - The Door to Chthon:

#1 - From the start, jump down. To the left will be a corridor. At the end
is a design suspended over lava. Ahead of that is a door which opens as you
walk down the corridor, and to the left is another door. Enter the door
ahead of you. Turn to the right. There should be an obvious, but still
hidden door ahead and a room forward and to the right. Walk in front of
that room. Turn to face away from the room and look up. There will be a red
Q symbol and a system of air ducts. Shoot it. The hidden door, now to your
right, will open. Ride the lift up onto the air ducts. Walk to the edge and
look down and to your left. You should see the celing of the room below.
Jump onto the celing. There will be a quad damage powerup there.

#2 - Go to the room to the left of the design suspended over lava. Push the
button with the Q. Fall into the pit that opens behind you. Wait for the
stairs to form and then walk down them. There is a passage with a 100
health item at one end and a spiked wall at the other. As you walk down 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
be able to jump to a landing with a 100 health box.

#3 - Below the start is a completely dark room. Once you get the silver
key, this room lights up. Cross the pit in this room and go to the end of
the passage. Turn left. You should be facing a set of stairs with a closed
door at the top. To the right of the stairs is a column and a large chamber
with a Q switch in it. Hit the switch. Go to the side of the column that
