Other points of interest[edit]


  1. Use the wall south of the start to get a chainsaw. (sector 135)
  2. When you see the chaingun, look at the ledges behind it to see ammo clips, a box of ammo, a box of shotgun shells, and shotgun shells. It is possible to get near the windows of these ledges, then enter them from an angle to get to these ledges, which count as the same secret. (sector 29)
  3. Open the door north of the crates. In this room, flip a switch behind the translucent wall to the southwest. Head to the west room with nukage and fall into the central hole. Use the northwest switch, which raises a bridge on the walkway leading west through a translucent wall. Flip the switch behind that wall to get a backpack and a soul sphere. (sector 84)
