Other points of interest[edit]


  1. Exit the starting area and head down the steps to the left, but look north as you do to find a section of the wall with a gray ridge at the bottom. Use this side of the wall to find a green armor, a medikit, and ammo clips. (sector 24)
  2. Ride the blue key lift up to the blue door, then press on the northeast wall to access the other side, which has health and armor bonuses. (sector 58)
  3. Approaching the rising and lowering lift in the northeast part of the map causes a different lift to lower. Go back west and through the opening before it closes to find two boxes of rockets and a megaarmor. (sector 74)
  4. Head past the rising and lowering lift to the north end, then take the first path you see going south. You will find a rocket and a candelabra in a side room. Press on the wall below them to find health and armor bonuses. (sector 83)
  5. Press on the wall west of where the rocket launcher is to find health and armor bonuses. (sector 88)
  6. Head east from the starting hall and south across the nukage to a door. Open it, and in the next room, climb on the crates at the southwest end. Look southeast and shoot the switch, then leave and go to the red key area. Head south and west into the room that had the shootable switch, where the southwest wall is now open. Inside is a plasma gun, two health bonuses, and two armor bonuses. (sector 147)
