Other points of interest[edit]


  1. After using the switch in Secret #2, go to the area with supplies a bit to the west of there. The path to the west is open, so grab a radiation suit and go that way. As you do, hug the north wall to go through, then keep going west, then north at the next fork, and you will eventually get to a BFG9000. (sector 160)
  2. Enter the large lava pit in the center and head north into the corridor. Head east and keep going east as much as you can until you get to a switch, which is the secret. Note that although the sector where the switch is is small, you can still register it if you hug the wall. (sector 164)
