Other points of interest[edit]


  1. At the start, head towards the door and open the north wall with ridges at the top for a shotgun and boxes of shotgun shells (the latter will not appear on Ultra-Violence or higher). (sector 50)
  2. Open the door, continue along the hallway, and flip the switch. The big hall with the intersection counts as a secret and is impossible to miss. (sector 45)
  3. Head west at the intersection and when the path goes north, go to the southwest corner for a lift down. This area has a backpack, as well as a box of shotgun shells and a box of ammo if you are playing on Hurt Me Plenty or lower. (sector 5)
  4. The switch inside Secret #3 opens some bars west of the blue key, with a megaarmor behind those bars. (sector 98)
  5. In the blue key room, face the east wall and shoot at the wall a bit south from the armor bonus but a bit north from the medikit. If you do it right, a section of the wall opens up. Head down the steps, take the lift, and flip the switch to get a chaingun and boxes of ammo (the boxes of ammo do not appear on Ultra-Violence or higher). When you step on the platform with the chaingun, a wall opens up leading back to the blue key room, which is the secret. (sector 128)
  6. Enter the small corridor with the shotgun south of the blue key and flip the switch. Return to Secret #3 and the path southwest will be available. In the next room, open the south wall to get armor bonuses, boxes of ammo, and a box of shotgun shells. Look out for demons that appear from the wall to the south. (sector 61)
  7. In the same room mentioned above, flip the switch and take the lift up to get a soul sphere. (sector 68)
  8. Jump into the courtyard below Secret #6 and flip the switch at the northeast side to open the east wall which has former humans and a chainsaw. (sector 70)
  9. In the yellow key area, enter the northwest corridor and use the switch there. Quickly leave the corridor and head through the lights just south of the corridor, which opens a wall at the southeast end of the area. Run up the steps there before the door closes to get to a room with a medikit, health bonuses, and a radiation suit. (sector 34)
  10. Follow the path beyond the radiation suit in Secret #9 and you will soon find a rocket launcher. (sector 13)
  11. In the room past the yellow door, use the fake exit switch to open the side closets. Enter the east closet and head north into a hall. After the second turn in the hall, lower the west wall to find armor bonuses and a computer area map. (sector 91)
