Other points of interest[edit]


  1. Head a bit southwest from the starting point, then go to the east wall and press on the orange wall to find a passage with two health bonuses, two armor bonuses, and a box of shotgun shells. (sector 51)
  2. In the red key area, head to the southeast end and use the switch there, then get to the middle lift which has lowered. Ride it up to find health bonuses, armor bonuses, a medikit, and a box of ammo. (sector 72)
  3. In the hall east of the red key area, press on the north wall in the small dead end to find a room with a green armor, a box of shotgun shells, an armor bonus, and two health bonuses. (sector 208)
  4. If you head right in the room where Secret #3 is, follow the passage to a switch. Flipping it opens the northwest wall in the room. Follow that passage to get a light amplification visor. (sector 201)
  5. Open the red door and head to the northwest part of the hall. Flip the switch to open a nearby wall that leads to a soul sphere and a teleporter back to the start. (sector 188)
  6. At the north end of the blue key area, find the terminal at the north end of the long computer block and use it, which reveals a switch behind you. Flip it, then head to the west of where the blue key is to find a passage of health and armor bonuses. (sector 90)
  7. Take the lift at the end of Secret #6, then on this ledge, take the other lift here leading down. This passage contains a chainsaw and armor bonuses, and the steps that form where the armor bonuses are leads to shotgun shells. (sector 54)
  8. In the area past the blue door, climb the steps and head around to the south end until you hear a lift lower. Quickly head back to the north end and into a passage containing health and armor bonuses. This passage leads to stimpacks and shotgun shells, just before you have to cross the nukage going south. At the end is a backpack, shotgun shells, health bonuses, and armor bonuses. (sector 150)
  9. In the room just before the room leading to the exit, press on the north end of the center computer block to lower a lift to the south. At the top of the lift, go left and use the wall to get a computer area map. (sector 37)
