Other points of interest[edit]


  1. From the starting point, walk along the slime creek towards the metal bars. In the next room, press the radiation hazard sign you're looking at to open those bars. Enter the slime steps (sector 103) dressed appropriately to get a light amplification visor.
  2. In one side wall of the stomping door (sector 498; not to be confused with the big stomper behind the blue door) there is an inconspicuous switch. Press it, and quickly run down the aisle where you spotted an invulnerability before on a pedestal which is now accessible for a short time. (sector 496)
  3. In the hallway behind the yellow door, getting your hands on the blue key opens an alcove (sector 727) in the far side of the hallway that holds a megaarmor ready for you.
  4. When you enter the slime circle in the south, make sure you wear a brand new radiation shielding suit. Turn left and circle the course a few times. Each time you pass the finish line, the gate to the center of the room (sector 760) is lowered a little bit more. When the work is done, you can collect a soul sphere along with some more useful stuff.
Exit to secret level - as you approach the end of the level, choose the eastern one (sector 245; marked "XXXI") of two exit doors to enter MAP31: Hell's Armoury.
