Other points of interest[edit]


  1. In the nukage tunnels, go towards the radiation suit, then turn north to find a wall lowering. Behind it is another radiation suit, a medikit, and a switch. (sector 237)
  2. Go back to the beginning of the nukage tunnels after flipping the switch in Secret #1 and into the red hallway that has now opened. Follow it all the way to a large room of dead bodies and doppelgangers, then use the teleporter. Head to the northeast part of the room you come to for a switch that opens the secret exit. (sector 132)
  3. In the room with the secret exit switch, leave via the other teleporter to reach a backpack. Leave the area through the west wall to get a light amplification visor. (sector 218)
  4. See Secret #3. (sector 407)
