Secrets[edit]

  1. Take the west path at the start and in the next room, go to the east wall and use the south part of it to find a rocket launcher and a path back to the start. (sector 195)
  2. In the same room where you got Secret #1, take the west lift and go north until you see two health bonuses. Open the east wall at the first one and follow the passage to a megaarmor. (sector 187)
  3. North of Secret #2, open a wall at the corner to get a computer area map. (sector 217)
  4. Drop west of Secret #3 and take the northwest path. Once you enter the west side, quickly run back east on the path you came and then in the bigger room, go to the west wall with the terminal to ride up. Lower the terminal to get a chainsaw. (sector 214)
  5. Just before the blue key room, use the northeast wall to find a passage outside to armor bonuses and a chaingun. Grabbing the chaingun opens a wall to the south for a medikit, a backpack, and a switch. (sector 165)
  6. In the north maze, the central sections blink. Go to the southernmost of those sections and open the east wall to find a passage leading to a soul sphere. (sector 81)
  7. In the exit ring at the east side, the southwest wall will be open if you flipped the switch in Secret #5. Enter it for a medikit, health bonuses, a box of shotgun shells, and partial invisibility. (sector 210)
