Other points of interest[edit]


  1. The room with the crates containing the switch which opens up the corridor to the blue key room has a secret door to the north (marked with a misaligned texture) leading to two shotgun guys (one on easy skill), a rocket launcher, a box of rockets, and (on multiplayer) a box of shotgun shells. (sector 404)
  2. The blue key room has a secret door in the north-west leading to a soul sphere. (sector 242)
  3. In the east is a large room with a rocket launcher and some boxes of rockets. This room has a secret door on the west wall leading to a partial invisibility. (sector 462)
  4. North-east of the central room is a room with three switches on a panel. Part of the ledge here has a different texture - it lowers on pressing, allowing access to an area with 1-3 imps, two medikits (one on easy skill), a backpack, and some ammo. (sector 129)
  5. There is a secret lift in the north-east of #3 leading to an area with a soul sphere. At the south of this area is a lift which lowers on pressing the western wall, allowing access to an area with two imps (one on easy skill) and a chainsaw (there is also some ammo on multiplayer). (sector 128)
  6. The closet six to the east of the yellow key closet has a switch which lowers the floor, allowing access to a maze. Directly opposite this lift (to the north) is a secret door leading to two medikits (one on easy skill), a third medikit (multiplayer only, not on easy skill), a box of rockets, an energy cell pack (two on multiplayer, three on hard skill multiplayer). On easy skill there is also a plasma rifle - on other skills the plasma rifle can be obtained by opening a secret door to the west (where there is instead an energy cell pack on easy skill). (sector 334)
  7. After going through the yellow door to the west, head through two more doors then turn south and through one more door. Carry on ahead - a door will open ahead revealing a monster closet. This closet has a secret door to the south leading to a soul sphere and a box of bullets. (sector 391)
  8. After the floor of the central area is lowered, there is a secret door to the north-east (marked with a green texture) that can be opened, revealing an invulnerability. (sector 431)
  9. Just before the exit is a secret lift to the north, leading to a baron of Hell (two on multiplayer) and two medikits. (sector 176)
