Other points of interest[edit]


  1. At the large area on the left side of the map are two pits next to the entrance. Drop into the one at the south end, then enter the room and use the teleporter. Head southwest and around the bookshelf containing the supplies, which will open up a block behind you with several former humans on it. This block has a switch which will lower the bookshelf, allowing you to get a super shotgun, shotgun shells, and stimpacks. (sector 30)
  2. Use the red key to enter the wooden area, then use the lift to the north. At the top, drop down at the far end and use the switch in the southwest corner, then leave the room. The door to the south should be open. Enter and notice the misaligned texture to your left. Open this wall for a plasma gun. (sector 201)
