Other points of interest[edit]


  1. After you get the blue key, return to the loop at south of the building it was in and the east wall will go up and down. Ride it and go around to get a soul sphere (megasphere on Hey, Not Too Rough or lower). (sector 131)
  2. After getting the red key, go around the perimeter again until you are at the north side. Go southeast and through the misaligned wall to get a berserk pack. (sector 240)
  3. At the south building, head to the south ledge and look north, shooting the eyes. This reveals a passage to the right to get a box of rockets, health bonuses, shotgun shells, an energy cell, and a soul sphere. (sector 343)
  4. Just before the blue key, open the north wall to get an energy cell and a megaarmor. (sector 416)
