Other points of interest[edit]


  1. In the westernmost room with crates, use the northwest switch and go to the southwest crate which is now open to get a box of ammo or a plasma gun depending on your skill level. (sector 217)
  2. In the same room, use the switch at the south end and return to the northwest corner. Enter the teleporter and use the southeast lift to get either an energy cell or an energy cell pack depending on your skill level. (sector 215)
  3. In the same room, use the southeast lift, then as it rises, quickly jump to the crate with the berserk pack. An alternate way to get this secret is to use the switch at the east side of the blue key room, return to the crate room, and climb the steps near the south side to be able to jump to the berserk pack. (sector 33)
  4. In the blue key room, use the computer where the key is and go left of the terminal as well. Leave and take the teleporter to the east to get a soul sphere (only on Hey, Not Too Rough or lower). (sector 194)
  5. Leave the previous secret and open the blue door. Flip the switch, then return to the crate room and climb the stairs (assuming you have them there). Take the teleporter to get a green armor. Take the corridor to get shotgun shells (not on Hey, Not Too Rough or lower). (sector 296)
  6. See Secret #5. This is the green light to the north of the secret that is not accessible. (sector 305)
  7. Open the blue door in the hub and head south to the second door on the east. Open the west wall here and get armor bonuses, a computer area map, and a stimpack. (sector 63)
  8. In the yellow key room, use the terminal to the north. Enter the hub and take the watery steps at the east side to find a hall with health bonuses, ammo, a shotgun, armor bonuses, and a berserk pack. (sector 149)
  9. In the north field, go to the northwest wall. Use the valve above you and head directly south to the lift that lowered to get a soul sphere. (sector 24)
