Other points of interest[edit]


  1. At the south area, find the section of the south wall that the light does not shine on and use it to reveal a hidden switch. Use it to open the hall to the east, with several rooms. (sector 279)
  2. Head north from the yellow lights at the south end and go behind the crates to get a medikit (stimpack on Ultra-Violence or higher) and ammo clips. (sector 37)
  3. In the room with crates, a single rocket is located in the middle. (sector 290)
  4. In the room with crates, do not shoot the barrels. Jump on them and jump to the crates at the top, then go west to get a health bonus, a medikit, an energy cell, armor bonuses, a box of rockets, and a switch. (sector 311)
  5. The switch in Secret #4 will open the north door, where you can get a super shotgun. (sector 36)
  6. After you get the red key, return to the start and take the south door. Open the red door and crouch to get a plasma gun to the south. (sector 205)
  7. In the red maze west of the start, find the switch, which opens the north wall in the hall. Outside, head to the northeast to get a rocket launcher. (sector 266)
  8. This secret is the high ledge near Secret #7, which can be accessed by rocket jumping. Up here is a medikit, an energy cell pack, and a soul sphere. (sector 23)
