Essentials
Emerge and grab the shotgun in the middle if you need to, looking out for imps who teleport from the windows. If you are in the middle of this room, there are stairs on the west and east sides. This area has four ways of travel. Go north first, towards the area with Wolfenstein 3D textures, and go all the way to the switch that you see on the right. Look out for the enemies behind you after you press it, and head back to the entrance of this area. This time, go left towards the open passage, and three walls will open up revealing several monsters. Head towards the closet that had a lone imp in it and the wall will open revealing a chaingunner and a blue skull key. Return to the main room and head south. In this gray room, there is a teleporter right here, as well as another one if you climb the steps. Take the one on the ground first, and take the subsequent teleporters (picking up a super shotgun along the way) until you arrive on a small platform to the east. Turn right and hit the switch here. Now take the teleporter at the top of the steps and take the subsequent teleporters until you arrive at the platform with the corridor. Grab the yellow skull key at the end of this corridor, and watch out for imps that teleport into the area. Go back to the main room and head west, through the yellow door. In this room, manuever around the computers to the north side of the room and hit the switch here. This will lower several computers in the room with monsters. One has a box of shotgun shells and the other has the red skull key. Make sure you grab the key, and then return to the main room going east this time. In this terraced area, head for the far right corner and you will find the teleporter to get out of here. Press the furthest panel from the right to exit.

Secrets

 * 1) In the Wolfenstein brick room, one of the computer panels in the northwest corner is not blinking.  Open it to find security armor. (sector 168)
 * 2) Similarly, one of the computer panels in the south of the room is not blinking.  It can be opened to reveal two medikits (Hurt Me Plenty or lower,) or a soul sphere (on Ultra-Violence or higher.) (sector 166)

Routes and tricks
As with many other levels in Icarus that have "teleporter" or "begin simulation" exits, a death slide can be performed on this level in the exit hall. Because the only rocket launcher on this level is multiplayer-only, you must let a monster kill you to pull it off. It is possible to lead imps from the final, wooden room through the simulation portal, and let them damage you heavily, before running toward the exit as they throw fireballs at you, making sure one kills you. If done correctly, your corpse will slide under the barrier, and into the teleporter, ending the level.
