Other points of interest[edit]


  1. At the northeast end in a room with crates, take a lift up and head north to a room with three barrels and a computer terminal. Open the northeast wall here to get a soul sphere and a box of ammo. (sector 398)
  2. On the large lift at the northeast end, lower the lift and while it is lowered, head to the north wall. Head north through the opening as the lift rises to enter a room with a megaarmor, a medikit, a box of shotgun shells, and a box of ammo. The switch at the north wall here lowers the central column on the large lift, allowing you to collect armor bonuses. (sector 414)
