Secrets

  1. When you reach the large room on the north side of the map, look south and go through the vine. On the ledge here, look at the vine-covered wall on the east side with the silver ridges around it and open it. This secret room contains shotgun shells, rockets, a medikit, and a switch. (sector 129)
  2. In the room directly west of the yellow key room is a large lift. Ride it up, and find the computer terminal with the monitor on it. Open it up to find a rocket launcher, a medikit, and two rockets. (sector 191)
  3. In the nukage surrounding the yellow key area, press on the wall at the southeast corner for a lift, where you can collect a backpack and stimpacks. (sector 200)
  4. The switch in Secret #1 opens a door on ground level just south of where the switch is. Go through this door, making sure to pick up a radiation suit as you hop into the nukage going south. As you do, look for a brown wall. Open this wall and follow the passage to a secret room with numerous supplies and a teleporter. This teleporter takes you to the cage in the middle of the room with a soul sphere. (sector 221)
  5. Near the yellow door, find a gray wall that has some slime on it and open it to find a spectre (or two) guarding a medikit and a backpack. (sector 236)
  6. When you press the switch that reveals the yellow key, you also open up a monster closet behind you. You can open the central wall in this closet, revealing passages containing rockets, shotgun shells, health bonuses, and armor bonuses. (sector 296)
  7. Open the yellow door and climb the steps. At the top, go to the northeast corner and open the wall here for a stimpack and a switch. This switch opens the door in the previous room, the door that was south of the yellow door, allowing you to head outside and around. (sector 349)
