Other points of interest[edit]


  1. From your starting point, head to the building to the left of the one you start on. An entrance is on the north side. Enter the corridor and use the silver lift to head up, then at the end of the area press on the skull to reveal a teleporter. This will take you to a room with caged demons, and at the south end of the room is partial invisibility. (sector 44)
  2. Once you have the red key, go to the building to the east of your starting point. Take the stairs up and use the lift, then at the top, face towards the opening to the south. Jump down here to get stimpacks, boxes of ammo, shotgun shells, and a green armor. (sector 428)
  3. The switch at the top of the red door building opens some windows to the east as well as the door to that building. Enter and use the big lift to head up. At the top, flip the switch at the east end to open up the northwest wall. The wall with stripes on it is a lift that leads up to one of the windows. Up here you can get an energy cell, a box of ammo, and a medikit. (sector 499)
  4. At the long expanse in the southeastern part of the map, fall into the nukage to the north of the bridge you are on and go northeast. There is a hidden radiation suit in the nearby corner if you need it. Go along this passage until you reach a large room with a silver lift. Ride it up all the way and flip the switch at the top, which will open up a room with a shotgun guy and an imp in it, but will also open a wall to the north, which is accessible from a different lift. Take your lift back down and get off to the south, then go east and to the rightmost lift there. In the next room, the lift is to the northwest, take it down and you should then access the secret which has a soul sphere and a box of rockets. (sector 317)
  5. At the east end of the building requiring the blue key is a vending machine west of the teleporter. Use the buttons on the vending machine to reveal a soul sphere. (sector 200)
  6. Now use the teleporter mentioned above, and there will be a terminal to your right when you emerge. Using it causes the wall ahead of you to lower. Take it down to a nukage-filled room and on the west wall where the lamps are, you can open the wall here to get a box of ammo, a box of rockets, a backpack, and a stimpack. (sector 32)
  7. The sector where the secret exit is, which is accessible from the caverns north of the northwesternmost building, counts as a secret. (sector 105)
