Secrets[edit]

  1. The path south of the pillar with the switch that opens up the route to the blue key has a lift leading to a room with some items. En route to this room is a secret door to the west (marked with a different texture), leading to an outdoor area with two boxes of bullets, 4 shotgun shells (neither present on easy skill), three armor bonuses, 4-6 shotgun guys, and 0-3 imps. (sector 171)
  2. The door immediately before the door opened by the aforementioned switch (leading to the blue key area) counts as a secret and is impossible to miss. (sector 81)
  3. East of the red door is a path leading to a lift to a health bonus. There is a secret door to the east here leading to an armor. (sector 37)
  4. North of the blue door is an alcove with a box of shotgun shells (hard skill only). The back wall of this is a secret door leading to a chainsaw (hard skill only) and a switch which opens up the windows to the outdoor area. (sector 147)
  5. The nukage surrounding the yellow key counts as a secret and is impossible to miss. (sector 16)
  6. En route to the yellow key area is a path leading to a lift - at the top is a secret area mirroring #3, leading to a medikit. (sector 41)
