Other points of interest[edit]


  1. Near the two red doors, shoot the barrels near the south wall and open it to find boxes of ammo and stimpacks. (sector 68)
  2. Head south on the ledge where the red key is and lower the south wall to find a passage of health and armor bonuses and a box of ammo which lead to a blue door. (sector 36)
  3. Take the lift between the red doors and take either path to raise a bridge leading to a switch. Flipping it reveals two monster closets at the steps behind the red doors. Open the red door going south and enter the closet there, then press on the west wall in the closet to find a passage of health and armor bonuses. (sector 82)
  4. At the end of Secret #3, open the wall to go back to the starting point, where the next wall to the east will also lower. Enter this passage to find more health and armor bonuses. You will eventually drop to a computer area map. (sector 72)
  5. In the nukage at the west end of the map, head to the east to find health bonuses, armor bonuses, and a light amplification visor. (sector 237)
  6. In the nukage at the west end of the map, take the southwest passage to a platform with a box of shotgun shells, a box of ammo, two armor bonuses, and the blue key. (sector 210)
  7. Continue east past Secret #6 to find another platform with a health bonus, two armor bonuses, and a megaarmor. (sector 232)
  8. After you get the blue key in Secret #6, return to Secret #2 and open the blue door to find two armor bonuses, a medikit, a soul sphere, a box of ammo, a box of shotgun shells, and a switch. (sector 190)
  9. The switch in Secret #8 raises a bridge to the south. Go back to that area and cross that bridge to the wall. Open the wall to find a lift leading to a stimpack and the secret exit. (sector 77)
