Other points of interest[edit]


  1. In the southeast part of the base's first floor, near the crates, use the metal grating on the west wall. This will reveal a soul sphere. (thing 329 via thing 330, ZDoom's "secret trigger" actor)
  2. Enter the powerplant and at the fork, turn left. There will be a lift to your immediate left, but also a metal panel a bit past the vent on the west wall. Jump up here and open the panel for a berserk pack. (sector 921)
  3. You need the yellow key for this secret. Head through the north door in the room where Secret #1 is located, and take the north lift up. Shoot the vent on the left and hop into the hole to reach the vent shaft. Shoot the shadows as you continue east, then south. At the dead end, flip the switch (which requires the key) and keep going through the room of health bonuses and rockets to the next vent. There is a hole in front of the armor bonus in the next vent. Drop into the hole to reach a secret room with two friendly marines, a shotgun, a computer area map, a box of rockets, energy cells and medikits. (sector 5112)
  4. Enter the powerplant and at the fork, take the door straight ahead. Jump down the hole in the control room above the reactor to reach the hidden vent area where you can get a number of supplies, including a plasma gun. (sector 5770)
