Other points of interest[edit]


  1. Climb the steps in the northwest section and a wall with chaingunners (only one on Hey, Not Too Rough or lower) opens. Use the steps to jump to that wall and open the back wall to find armor bonuses, medikits, boxes of shotgun shells, and a super shotgun. (sector 181)
  2. In the crate room at the northeast end, find the switch at the northeast end and use it, then go in between the crates on the east wall to find boxes of ammo, stimpacks, a berserk pack, and eleven health bonuses. (sector 160)
  3. In the metal hall at the east end, press on the lion face to get a rocket launcher and rockets. (sector 193)
  4. In Secret #3, use the lion switch, then return to the metal hall and continue south to the edge. Shoot the switch to the northwest to raise a walkway that forks to a megasphere. (sector 170)
  5. Go back through the metal hall and flip the switch if you have not already done so to raise a walkway going west to two more switches. Press on the northwest wall here to find stimpacks and shotgun shells. (sector 356)
