Other points of interest[edit]


  1. After getting the blue key, return to the starting point and use the big blue door. Take the steps and jump to the left teleporter, then take the left teleporter in the next area. Open the nearest door and in this room, press on the back wall to find a medikit and a backpack. (sector 193)
  2. Open the door to the east of the chainsaw, then take the south hall. About halfway through the hall, a door opens in the previous hall near the entrance. Go back and enter the secret room for shotgun shells, shotgun guys, zombiemen, and three switches. The left and right switches open up nearby alcoves with shotgun guys and health bonuses. (sector 227)
  3. Use the middle switch in Secret #2 and go back to the door leading to the starting hall. Go through the north wall near the door and up the steps to a secret room with a soul sphere and a computer area map. (sector 236)
  4. Go to the south end of the starting hallway and look at the east wall. Find the section that is cleaner than the rest and use it to find a room with imps, a shotgun, and a berserk pack. (sector 391)
