Other points of interest[edit]


  1. At the start, head north from the bookshelf and use the skull switch. Head east, then north and open the door. In the next hall, there will be an open room with a medikit, an ammo clip, and shotgun shells. (sector 142)
  2. In the area with the damaging floor and flickering lights, head for the west end until you find a hall with a candelabra and a pillar, just before two blue torches. Go through the west wall which is misaligned to find a soul sphere. (sector 101)
  3. Head southeast from the red key to find a BFG9000. (sector 198)
  4. In the maze past the yellow door, head to the northeast side and open a door to a room with a switch and another block. Ignore them and open one of the west walls between the bookshelves to find health bonuses, ammo clips, a box of shotgun shells, and an energy cell. (sector 217)
