  1. In the room past the red door, the floor will lower as you approach the switch. Enter either of the damaging slime pits and flip (or shoot) the switch on the east side. The room that connects to both has all the weapons, a backpack, a radiation suit, and several powerups. (sector 59)
  2. At the northwest wall of the big area, go towards the teleporter at the northeast end. When you emerge, shoot either the left or right walls to find a room with lots of ammo, partial invisibility, an invulnerability, and a soul sphere. (sector 62)
