Other points of interest[edit]


  1. After going through the first door, you will see a secret door, marked with a green texture, immediately behind the sign. It leads to two clips and eight shotgun shells. (sector 276)
  2. In the north of level is a water room with a structure in the middle. There is a secret path to the east of this room, accessible by leaving the water room through either exit, heading immediately east and opening a secret door across from the short red firestick. The path contains an armor and a stimpack (two stimpacks on easy skill). (sector 119)
  3. In the north-west of the water room is a section of wall with a less green texture. It is a secret door, leading to a computer map and a light amplification visor. (sector 122)
  4. The west side of the structure in the water room has a lift which lowers on approach, leading to a medikit (two on easy skill) and a backpack. (sector 136)
  5. After going through the southern red door, you will enter a square room with a demon face on its east wall. This lowers on pressing, revealing a room with two stimpacks, two boxes of bullets, and a switch which reveals a chaingun in the square room. (sector 31)
  6. The path immediately at the bottom of the stairs in the southern maze area counts as a secret and is impossible to miss. (sector 249)
  7. Go up the stairs in #6 and follow the path to the end. Ahead at the end is a secret door leading to a rocket launcher and a megaarmor. (sector 17)
