Other points of interest[edit]


  1. Enter the damaging blood and press on the marble wall with gargoyle faces to trigger a lift. A plasma gun, armor bonuses, and a medikit are on it. (sector 87)
  2. On the hallway leading north to the blue door where the exit is, look to the northeast and shoot the switch to open a nearby compartment with stimpacks and a switch. Go southeast after you flip the switch to the big room, where the north wall lowers revealing a secret room with energy cells, armor bonuses, a soul sphere, and a computer area map. (sector 118)
  3. At the westernmost room with the switch to open the southernmost rooms, the terminal on the south wall has a recessed terminal you can use. It will open up a secret room to the right with partial invisibility, armor bonuses, stimpacks, and boxes of rockets. (sector 217)
  4. From the red key, jump to the crate containing the lone health bonus to trigger a lift. Run left up the steps and to the north to the megaarmor and rockets before it closes. (sector 286)
