Flip the switch in front of you to lower the walls and reveal a room with imps, then go up either of the staircases and walk east or west to a nukage pool. Step through the nukage, then climb up another set of steps and look south to see the red keycard, which is guarded by shotgun guys, imps and a demon on Hurt Me Plenty (HMP) skill level or higher.

With the red key, go back to the starting room, passing some imps and zombies that have been released near the nukage pools, then go east past another nukage pool to reach the red door. Open it and kill any waiting demons, then go up the steps behind them to collect a berserk pack which is guarded by shotgun guys. Go up the northern staircase to a door and pass through it, which will open a teleporter ahead guarded by a cacodemon (the teleporter goes to a room to the south), then flip the switch in the south-east corner to lower a wall near the berserk pack you picked up. Pass through this wall to find some zombiemen guarding the blue keycard.

Go back to the starting room, where some spectres will teleport in, then open the blue door on the west side and head up the steps to reach the exit door. Open it to find the exit switch, which is defended by a spectre on HMP or higher.

Other points of interest[edit]


  1. From the spot where you found the red key, open the circuit panel on the west wall to find a partial invisibility. (sector 95)
  2. In the nukage pool by the red door is a small platform with a rocket launcher. Open the misaligned wall due north of this platform to find a radiation shielding suit. (sector 310) You should get this secret after obtaining the red key.
  3. Taking the red key opens a tunnel next to the aforementioned rocket launcher. With the radiation suit from secret #2, enter the tunnel to find a button and press it to raise a narrow ledge leading to the weapon. Taking the weapon opens an alcove behind it with a backpack, and an imp on HMP or higher. (sector 201)
  4. In the area with the northern teleporter near the blue key, press on the gray western wall to reveal a box of rockets, a computer area map and a medikit. (sector 241) The button here opens the passage to the outdoor area, east of the southern teleporter. In that outdoor area, you will find two boxes of rockets, armor bonuses and an armor.
  5. After grabbing the blue key, return to the starting point. The door here has opened, revealing a chainsaw and two stimpacks, as well as a spectre on HMP or higher. (sector 284)
  6. Go up either staircase in the starting room, then go to the window between the staircases and flip the switch next to it. Now go through the blue door and flip the switch that has opened on the south wall to open a passage near the western hallway that led to the red key, which leads to a supercharge. (sector 51)
