Other points of interest[edit]


  1. The room that contains 4 shotgun shells, an armor, and the switch that opens the third of the four doors leading into the main building counts as a secret and is impossible to miss. (sector 73)
  2. After going through the four doors into the main area, continue straight ahead to the wall. There is an unmarked secret door here leading to a stimpack, a medikit, and 8 shotgun shells (12 in multiplayer, where there also a berserk. (sector 86)
  3. Go through the teleporter north of #2, then turn right then left. There is a secret door by the short red firestick leading to a ledge overlooking the lava containing three imps, 4 shotgun shells, and a stimpack. (sector 240)
  4. The room south of the blue key containing the teleporter to the exit area counts as a secret and is impossible to miss. (sector 194)
  5. From the entrance to #3, continue south then west. On your right is an unmarked secret door leading to two stimpacks and a demon (two on hard skill). (sector 119)
  6. Opposite the door to #5 are two doors leading to a room with two staircases. At the top of these staircases is an unmarked secret door (next to a medikit on easy and medium skills) leading to a corridor with three imps. This corridor can also be reached via #3 by jumping into the lava and going up the stairs. (sector 142)
  7. The south wall of #6 has an unmarked secret door leading to a shotgun guy, 4 shotgun shells, and a stimpack. There is also a berserk on multiplayer. (sector 265)
  8. There is a door leading west from #6 to a corridor with some demons. The eastern wall of this corridor has an unmarked secret door leading to a stimpack and 4 shotgun shells. (sector 284)
  9. The lava pit overlooked by #3 has a door in the south wall of the northern part leading to two teleporters. Approaching this door opens up a door reached by heading north then east from the outside of the four doors leading into the main building. There are three imps (two on easy skill), a shotgun guy, a demon, and a backpack here. (sector 249)
  10. Near #8 is a corridor heading west. Go through the door at the end here - this opens a door north of the backpack in #9. Now walk over the north side of the platform west of the four doors leading into the main building (as hinted by the arrow on the floor behind #9). This lowers a lift north of the backpack containing a soul sphere - it leads up to a chainsaw and 8 shotgun shells. The lift can be lowered repeatedly. (sector 253)
  11. The staircase leading out of the lava overlooked by #3 has an unmarked secret door part-way up leading to a computer area map and (on multiplayer only, not medium skill) a super shotgun. There is also a chaingun and rocket launcher here - picking up either of these makes the other inaccessible. (sector 235)
