Other points of interest[edit]


  1. You can enter the building adjacent to the one you started out in by using the back door. Inside is a hole with a shotgun, a stimpack, and some shells. (sector 30)
  2. In the room with the red door, east of the door is an orange block. You can lower this block by pressing on its lower right corner, which looks different than the rest of it. The block lowers to reveal imps and a chaingun. (sector 82)
  3. Inside the room at the eastern part of the map, look towards a wall on the west side and notice a brown stripe of wall. Open this wall for a secret room with a berserk pack, a backpack, and armor bonuses. A zombieman will also be here on Hurt Me Plenty or higher. (sector 109)
  4. Near the yellow key pedestal, lower the wall on the left side to reach the outdoors. A medikit and a green armor are out here. (sector 337)
  5. From the entrance to the maintenance is a fork, with a hallway leading to the right and a lift straight ahead and to the left. Ride the lift up and look at the wall to the north. You will notice that the bottom part of this wall is brown instead of green. Open this wall to find a medikit, a chainsaw, armor bonuses, and shotgun shells. (sector 363)
