Overview
This map consists of seven sections linked by pairs of teleporters. Most of these move the player quite a distance, so it is easy to lose one's sense of direction; watch the automap carefully to see where you are.

Essentials
From the start point, go past the teleporter (A) to get the blue keycard (B). The glowing cross is actually a damaging floor (10% per second, or 5% on I'm too young to die), but if you straferun through it, you will not usually be hurt. Then go back and teleport.

Follow the large gray room around to the right, where there is a red slime "river". The bridge lowers as you step onto it, so cross quickly, and teleport again (C). You will emerge in a green brick room, where your path is blocked by a large platform (D). In the alcove ahead on your left are two skull switches; click the right (south) switch to lower the platform. Proceed west and then around to your left to the blue door (E). Go through and teleport.

Now walk forward through the dark green room until you are nearly at the far wall, then turn around. You will see a red button on your left, to the northwest (F). Press it to raise some stairs just ahead of you and to the right. Go up the stairs and click another red button (G). This opens up a teleporter near the first button (H).

Teleport yet again. Walk forward to lower the wall in front of you, which reveals the exit door (I).

Other points of interest
The red triangle in the large gray room (P) is also a damaging floor. Try not to spend much time there.

One of the square islands in the red slime river (the one with the shells and armor) also sinks as you step onto it.

If you play on Ultra-Violence or Nightmare!, there is a Cacodemon hiding behind the lowering wall in the last room.

Secrets

 * 1) After crossing the red slime river, click the switch on the wall to your right. A small block will rise out of the floor behind you, with two red buttons on it. Push the button closest to you (on the east side), which opens a short hallway next to the teleporter (J), containing a medikit and the red keycard. (sector 5)
 * 2) Push the other button on the small block (west side). This opens a teleporter (K) next to where the blue key was. Follow it to a secret room with a plasma rifle (L), which is guarded by two sergeants and a Demon (I'm too young to die and Hey, not too rough), or two sergeants, a Demon, and a Cacodemon (Hurt me plenty), or two sergeants, three Demons, and a Cacodemon (UV and NM). (sector 3)
 * 3) In the alcove in the green brick room, the left (east) switch raises part of the wall to reveal another teleporter (M). Follow it to a long hallway (sector 52) containing health potions and spiritual armor (N). Note that this area can only be opened once from the outside.
 * 4) The red door is just to the north of the blue door, surrounded by a pool of blood. Behind the red door is a room (sector 91) containing a blue armor and a computer map (O). These are guarded by a sergeant (ITYTD and HNTR), or three sergeants (HMP), or three sergeants and a Spectre (UV and NM).

Routes and tricks

 * If you are going for 100% secrets, take the first teleporter when you first come to it. After clicking all the switches at the end of the hallway, teleport back to get the blue keycard and teleport to secret #2 at the same time.
 * It is not necessary to click the switch that raises the short wall with switches on both sides. Just click in the air as if the wall had already risen.
 * You can collect secret #3 while waiting for the wall ahead to lower.
