 SECRETS LIST
All the official secret areas in the fourth episode of the Ultimate
Doom (Thy Flesh Consumed) are numbered and listed below, along with
the sector number, IDMYPOS coordinates, and decimal coordinates.
"Official" secrets are those which are counted towards the "Secrets"
total on the end level screen. Some non-secret areas which are hard
to find are also listed, but are not numbered. The information listed
below is for version 1.9 of the Ultimate Doom.
Also, there is a list of changes made in the first three episodes of
Doom between Ultimate Doom and the old registered version of Doom.
E4M1: Hell Beneath
1 69 ( -130, -409)
The room just south of the starting room has a pool of slime with a
walkway all around it. On the west side of the walkway is a door.
To the left of the door is a small niche behind the walkway; you can
see if it you look on the floor while standing on the walkway. Jump
down into the slime and hit the space bar on the south end of the
west walkway. This will lower a lift, revealing a niche with a
badly needed rocket launcher and some rockets. Inside the niche is
a secret door on the south side. This leads to a room with two
teleporters (#1). The left teleporter takes you to the ledge
northeast of the acid pool; the right teleporter takes you to the
ledge northwest of it.
2 30 < 3280000,ff640000> ( 808, -156)
The room behind the red door has a wall in the middle of the room,
with a path on either side of it. On the north end of the wall is a
small niche with a red torch. Hit the space bar on the niche, then
get the hell out of that room. This will lower the wall, revealing
id's excellent taste in music, and making it easier for you to kill
the imps behind the wall. Unfortunately, it will also let four
barons loose. When they reach the door, they'll teleport to the
west side of the acid pool. Also, don't walk on top of the newly
lowered wall (#2) until you've killed all the monsters, or you'll
cause a wall to be raised up all around you, trapping you inside
with the barons. There is a switch inside to lower the wall,
however. In order to get credit for the secret, be sure to walk
around slowly on the lowered wall without walking on the letters.
(The letters are not the secret.)
E4M2: Perfect Hatred
1 70 ( -618, 1552)
On the west side of the map, you will eventually find a teleporter
with three blue health potions right in front of it. To the left
of the teleporter is a secret door leading to a small room with a
beserk pack and some ammo (#1). In the northeast corner of this room
is another secret door, which leads to the north end of the teleporter.
Enter the teleporter from this end, and you will go to a room with
blue armor and a box of rockets.
2 74 ( -204, 1724)
3 17 ( -444, 972)
When you get to the area with the cyberdemon, don't bother trying to
kill him. Just walk north a little bit and pick up one of the
radiation suits or boxes of rockets. This will open the door to the
north, revealing some cacodemons. Run back south to get away from
the cyberdemon (either go down the steps, or jump into the slime).
At this point, a teleporter will be revealed in the center of the
map, to the north of the yellow key switch, between two sets of
steps. Enter the teleporter, you will land on top of the
cyberdemon, killing him instantly; there you will find a BFG (#2).
Hit the space bar on the ledge to the west to get out. When you do
this, you will lower the ledge, and also lower a lift in the slime
to the southwest. Jump down and run southwest to a small opening,
where you will find a switch that takes you to the secret level
If you drop down into the slime right between the two staircases at
the start, you will get a radiation suit. If you walk into the north
part of the slime pool by going northeast as far as possible and
then west and south, you will find a supercharger. Then, go to the
southeast corner of the slime pool; there you will find a staircase
leading up to an area behind your starting point; there you will find
some goodies and monsters.
In the room with the yellow key, there is an area to the south where
some barons were hiding. On the east end of this area is a hidden door
to a switch which raises a platform in the middle of the map. This
platform doesn't have anything on it, but it makes it easier to avoid
falling into the slime.
The ledge high up in the east area north of the blue key has nothing
in it but a cacodemon. You can't get up there.
E4M3: Sever the Wicked (max secrets: 90%)
1 71 ( -617, -550)
West of the starting ledge is a staircase leading down. South of
that is a staircase leading up, which leads to a door. Just before
you reach the door, a secret door opens behind you revealing an area
with some imps, and some other goodies including blue armor (#1).
2 124 (-1322, -2133)
3 125 (-1322, -1962)
4 127 (-1408, -1448)
5 128 (-1408, -1416)
6 129 (-1408, -1384)
7 130 (-1408, -1352)
8 131 (-1408, -1320)
9 132 (-1408, -1288)
10 133 (-1408, -1748)
11 134 (-1408, -1576)
12 136 (-1408, -1544)
13 137 (-1408, -1512)
14 138 (-1408, -1480)
15 147 (-1408, -1256)
16 148 (-1408, -1224)
17 149 (-1408, -1192)
18 150 (-1408, -1160)
19 151 (-1408, -1128)
20 152 (-1408, -1092)
21 154 (-1068, -940)
22 155 (-1344, -1040)
(This is not as cool as it looks. For some reason, they made a whole
bunch of adjacent sectors secret.) In the area south of the red skull
key, there is an area to the west with two torches and a switch.
The switch is supposed to open the door to that room, but I haven't
been able to get that door to that room to close. The sectors
containing the torches are secrets (#2, #3) but I was not able to
get close enough to the torches to get credit for those sectors.
Hit the space bar on the north wall to reveal a whole bunch of
secret sectors (#4-22), consisting of a staircase up to a room with
a supercharger and some other goodies. West of the switch is
another secret door with takes you to a teleporter back to your
If you walk straight east from your starting point and jump down, you
will get partial invisibility and a berserk pack.
E4M4: Unruly Evil
1 29 (-1096, -1232)
2 20 ( -936, -1112)
The first door leads to a room with a lift leading up to a ledge with
some monsters on it. The northwest corner of this ledge has a small
green torch in a niche. Hit the space bar on this niche to lower
a lift, revealing an area to the northwest with a berserk pack (#1) and
a teleporter to the south end of the map. The lift will also reveal
an area to the north with a rocket launcher (#2) and a teleporter
which takes you behind the door east of the ledge room.
In the southeast corner of the map is an area with some lava, an
invulnerability sphere, and twelve square platforms. Hit the space
bar on the north side of the northeast platform to lower it; this will
allow you to get on and walk over the platforms to the small room to
the southwest, where there is health. The second from the left in
the middle row of platforms also has a switch on the north side;
however, you can only hit it from the south. So, take the lift up,
and jump over to this platform, face north, and hit the space bar; this
opens a door to the north, which reveals a teleporter that takes you
to secret #2. You can also trigger the switch by standing on the west
side of the platform, aiming northeast, and hitting the space bar.
E4M5: They Will Repent
1 76 < 8c0000,feb20000> ( 140, -334)
The room with the red skull key has a red door in the southwest corner.
Behind this door you will find a room with a secret door in the southeast
corner; open it to reveal some health (#1).
2 151 < 2400000, 4e80000> ( 576, 1256)
To the left of the yellow door is another door which leads to a
teleporter; this teleporter takes you to the yellow key. To the
left of the teleporter is a hidden door with a berserk pack behind
The room with the red key has a column in the southeast corner which is
really a lift. There is a box of rockets on top of it.
The room on the south side of the blue door has a supercharger, in
the lava pit to the north; you may miss it if you're going too fast
when you jump down the first step.
The exit room has an invulnerability in the southeast corner, in the
slime. To get the BFG in that room, go to the room to the south, and
go up the steps and stand in front of the window to the west. Now
just jump down onto the ledge to the west of the exit switch. It's a
tricky jump, but it's possible. Now walk carefully along the ledge
to the east, and cross over to the ledge which the BFG is sitting on.
Remember that saving your game when standing on a narrow ledge does
not always work; use the automap to make sure that you're standing
exactly on the ledge, and not slightly off to the side, before
saving; otherwise, you'll fall off when you reload that game.
E4M6: Against Thee Wickedly
1 78 < de0000, 3ec0000> ( 222, 1004)
East of the starting area is a tower with an acid moat around it.
To the north and south are a series of small niches. On the north
side, the second niche from the east has a hidden passage behind it;
just walk through the back wall. There you'll find some goodies (#1)
including a plasma rifle.
2 132 < 33c0000, c0000> ( 828, 12)
Once you drop into the moat and enter the castle, you'll find a small
outcropping to the south with a radiation suit and a red torch. The
south wall has a secret door here (#2) which leads to a small room with
a blur artifact. The northwest wall of this room has a lift which
leads to a supercharger.
3 55 < 4780000, 5050000> ( 1144, 1285)
Once you drop into the moat and enter the castle, you'll find a small
outcropping to the north with a radiation suit and a red torch. The
north wall has a secret door here which leads to a series of passages.
One passage leads to some boxes of rockets, and a ledge which lets you
drop into the slime. Another passage leads to a baron of hell, and
a switch which will lower the yellow key. A third passage (#3) leads
to a lava pit with some cacodemons and a radiation suit.
It may make more sense to reach this secret another way. To do
this, get to the yellow key; notice that there are a series of
windows surrounding it with gratings covering them. You can walk
through the grating on the far right, allowing you to drop into the
slime. There's a radiation suit just to the south of you. The other
side of the pit has a secret door to secret #3 flanked by glowing
When you first drop into the slime pit, you should go to the tower
near the center of the pit. Lower the lift on the west side of the
tower, go up the lift and take the teleporter. This will allow you
to get the blue key. Then take the north side of the teleporter.
This will allow you to get the yellow key and another radiation suit.
Then take the east side. This will allow you to get the red key.
Once you hit the switch behind the red door, and take the teleporter
back out of the lava pit, you will be able to walk through the window
to the south to get a BFG which is on a ledge. There is also a
teleporter there, but don't take it yet, unless you want to face the
cyberdemon at close range. Instead, get a radiation suit if possible
(there are two of them in the lava pit with the red door) and walk
over to the southwest ledge, where you originally started. In the
south wall you will find a passage leading south to a ledge over an
area with some monsters. Jump down off the ledge and kill the
monsters. Then get the invulnerability artifact and take the passage
north into the lava pit. Now run north to the tower and take the
south lift up to the teleporter. This will take you to where the
cyberdemon is. If you're still invulnerable, you can easily take him out
with a BFG.
E4M7: And Hell Followed (max secrets: 50%)
1 262 < 100000,fa2c0000> ( 16, -1492)
2 263 < 440000,fa400000> ( 68, -1472)
3 264 < 640000,fa400000> ( 100, -1472)
4 250 < 1c00000,fbb80000> ( 448, -1096)
In the south part of the map, behind one of the yellow key doors,
you will find an area with a picture of a demon on the floor. In
ultra-violence mode, there will be a BFG on the south side of the
room. If you make any noise in this room, a cyberdemon (or a baron,
in lower skill levels) will teleport in, so don't shoot anything
until you get the BFG; at that point some bars will rise up on the
north and south side of the room; these just hinder your movement a
bit, and block the cyberdemon's rockets.
The south end of the room has a secret door leading to a small room
(#1) with various goodies. In ultra-violence mode, you'll get
invulnerability a soul sphere, and a rocket launcher; otherwise,
you'll have to be content with a few medikits. To the east of this
room is a secret door (#2) which leads to another secret room (#3)
with an invulnerability sphere. I wasn't able to get credit for
either #2 or #3; #2 is too small, and #3's floor is too high for me
Hit the switch on the north side of the room, then go east and then
south to a small room (#4) with blue armor, health, and ammo. There
are two switches in here which simply open the two yellow doors.
E4M8: Unto The Cruel
1 10 < 10d0000,feb00000> ( 269, -336)
Just to the southwest of your starting point is a small niche with
a twitching corpse hanging in it (this is the second niche from the
west). Hit the space bar on it to reveal a small area (#1) with
some ammo and a blur artifact.
There's an area to the south with blue armor on a pedestal. To the
west is a building with a lift going down. The lift leads to a
hallway with a pedestal at the east end. Behind this pedestal is a
secret door leading to a teleporter, which takes you to a ledge with
The room with the spiderdemon has a secret door just to the right of
the entrance. It contains a teleporter which leads to a room with a
(You get to this level via E4M2.)
1 53 ( -544, -1180)
There are two rather dark rooms (one on the west side and one on the
east side) which have a door on the north end and lifts on the west,
east, and south ends. They also have a series of small silver
columns. In the west room, go up one of the lifts and go near the
south door. To the left of the door is a secret door to a room
containing a berserker (#1).
2 234 < a00000, 8f00000> ( 160, 2288)
Just to the south of the exit switch is a secret door to a small
room containing a backpack (#2).
The yellow key is in the moat to the east of the starting room. It's
sitting on a narrow ledge, which you can jump onto from the north.
There's a plasma gun on a similar ledge to the west of the starting room.

 CHANGES TO FIRST THREE EPISODES
Except for the new episode, E1M1 is the only level that changed in
Ultimate Doom. The changes are:
1. There's a new switch on the pillar to the right of the staircase
which leads to the green armor. It's on the north side of the pillar.
It opens a door leading to the central area with the blue armor in the
acid pit. Walking through this door opens another door which allows
you to enter the central area from the room to the north (the room
behind the first door).
2. There are some new items in multiplayer mode. In the northwest
corner of the starting room is a shotgun behind some barrels. And
south of the staircase which leads to the green armor is a berserk
pack (skills 1-3 only).
