Other points of interest[edit]


  1. Use the east wall just south of the blue key to find a secret room with a chaingun and a box of ammo (Hey, Not Too Rough or lower), a stimpack (Hurt Me Plenty or higher), and/or a super shotgun and a box of shotgun shells (Ultra-Violence or higher). (sector 96)
  2. In the blue key room, head to the south wall and use the damaged part. Use the switch to lower a green armor. (sector 245)
  3. In the center of the round area at the south end, head to the northwest side and use the switch on the wall at the north end to raise two platforms leading east. Head to the area behind them and use the north wall where two health bonuses are to find a teleporter. When you teleport, head south to pick up a megaarmor. (sector 573)
  4. After teleporting to the northwest part of the map, head down and east, dropping to the nukage below. Head north, picking up a radiation suit as you go, and pick up the computer area map at this secret. (sector 705)


A revenant (Thing 418) in a closet in the east has no flags set for any of the three difficulty classes, so it does not actually appear in the level. It is at the same position as an imp on skills 1-3, so probably was intended to appear on skills 4-5. Also, four lost souls on skills 1-3 are outside the playable area in the west, so cannot be killed.
