Other points of interest[edit]


  1. Open the red door and go into the room there which will open the southeast closet in the previous room. Press on the wall with slime to find a hidden room with a switch. This switch lowers the block near the closet, and you can ride this block to get a box of ammo. (sector 28)
  2. In Secret #4, press on the green wall, then the switch. When you do this, quickly run west and open the yellow door, then head north before the next door closes to claim a soul sphere. (sector 60)
  3. In the southwest room, trigger the lift that goes up to the west and as it rises, jump southwest to the ledge there to get a box of ammo and a chainsaw. (sector 96)
  4. After crossing the bridge to the exit door, check the south wall that is slightly dimmed to reach a secret room with a switch. (sector 159)


A demon (Thing 27) and three imps (71, 126, and 133) have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
