Other points of interest[edit]


  1. Grabbing the red key reveals the south wall of monsters. You can find a box of shotgun shells, a medikit (only on Hey, Not Too Rough or lower). a berserk pack, and a green armor here (both of these not available on Hey, Not Too Rough or lower). (sector 98)
  2. From the red door, take two doors to the north and follow the winding path until you reach a platform with health bonuses (plus an armor on Hurt Me Plenty or higher). Stepping on this platform from the west side will open the south wall with several monsters, armor bonuses, and a stimpack inside. (sector 99)
  3. In the northern yard, take the lift in the northeast corner, then head west and to the platform with the switch, which lowers the room to the south. Although you need to enter this room to get to the switches that allow access to the blue key, this room counts as a secret sector. (sector 178)
  4. In the northern yard, take the lift in the northeast corner and use the blue skull switch nearby. At the top, enter the nearby compartment to find a green armor and medikits (or stimpacks on Hey, Not Too Rough or lower). (sector 227)
