Other points of interest[edit]



  1. When you first enter the outdoor area with a nukage pool and the red door, turn around and open the left small door. Go inside, down the stairs, and as soon as you reach the next room, turn around again and open the wall to the left of the staircase to reveal a secret closet containing an armor and a backpack. (sector 51)
  2. Open the red door and use the green pillar located immediately on your right. This will open up a secret area with a plasma rifle and some energy cells. (sector 82)
  3. When you get to the yellow key, notice that it's placed in a small niche in the wall, and to the left of it is another niche. Use that second niche, and a switch will appear between the two switches that you've seen just before (pressing the left switch is required to access the yellow key). If you haven't pressed the right switch, press it now and kill the mancubi, then press the newly-revealed middle switch to temporarily unblock yet another switch in the northwest corner of the area where the mancubi were. Shoot that new switch and immediately turn around to face a revenant ambush (only on HMP and above). The revenants have come out of a secret closet where you can find a megaarmor, two boxes of rockets and two cell packs, as well as four medikits. (sector 167)
  4. Open the yellow door and use the two purple lights to the left and right of the wall that has a skull on it. The lights will turn red, and the wall with the skull will lower to reveal a secret area with a soulsphere, a rocket launcher, and some rocket ammo. (sector 120)
  5. Open the blue door and cross into the final room. Now backtrack all the way to the starting area and open the demonic face opposite of where the chainsaw was. You may have to wait a little, but eventually, a secret closet will appear to your right, where you can grab a computer area map. Press the switch here to register this secret for the secret exit puzzle (see below for details). (sector 285)


To get to the secret exit, you have to find all five official secrets as well as press the switch in secret #5. Then return to the final room and press any of the four switches on the pillar within the central structure. If you've found every secret, the pillar with the switches will lower, and the secret exit switch will then appear in the starting area, on the north wall of the room where the chainsaw was. Press the switch to go to MAP32: Proceed With Caution.
