Other points of interest[edit]


  1. Head right from the starting area towards the lift, then use the wall with slime on it. You can find energy cells, boxes of rockets, and armor bonuses up here. (sector 49)
  2. At the hub, take the lower right path until you see stairs on your right. Take them up and open the door you see. The terminal to the south has a red bar which functions as a switch. Use it and leave the room via the door you used earlier, then quickly head west and south through the open terminal. Here you can find energy cells, rockets, a berserk pack, and a megaarmor. (sector 92)
  3. In the northeast outdoor area, the gargoyle switch at the north end has a backside. Use it and quickly run to the southeast, through a passage previously blocked by a beige wall. You can get rockets and a soul sphere. (sector 197)
  4. In the hub, take the southwest path, then south and east to a hall with some face switches. The gargoyle switch at the northeast end is not lit. Use it, then backtrack a bit to find a secret room open with medikits, a computer area map, and an energy cell pack. (sector 310)
  5. In the room at the southwest end of the map where you will get ambushed by a spider mastermind, use the switch at the top of the ledge, then the switch on the ground floor to open the bars to leave the area. Go back up to the ledge and go east and north to another ledge overlooking the curved staircase. Shoot the button at the northeast corner here to open a wall leading to a teleporter, which will take you to a soul sphere. (sector 333)
  6. At the northwest outdoor area, head to the southwest and enter the cave with lighter rocks going southeast. When you reach a stone wall area, find a wall that does not have slime on it and use it, revealing armor bonuses and a medikit. (sector 379)
  7. At the southwesternmost balcony, look to the east and shoot the switch to open a wall revealing a radiation suit, boxes of rockets, and a medikit. (sector 481)
