Secrets

 * 1) In the northeast nukage room, head north into the nukage and into the small tunnel. Head west and enter the northwest side room.

 * 2) Open the red door, then go into the nukage room where a switch is on the north wall. Use it, head back through the red door, then head southeast into an open room with armor bonuses and partial invisibility. (sector 285)
 * 3) Flip the switch in the blue key room, then quickly run east, up, and west. In this room, flip another switch at the east wall before it closes, then jump into the nukage and head north and east, onto a lift. Ride it up, then head south. On the east side of the middle column, open it to find a chaingun, a stimpack, and a computer area map. (sector 353)
 * 4) After going through the door that leads to the northeast nukage room, head east to raise some steps. As soon as you do this and climb the steps that were raised, head south and into the nukage, then towards the poison sign at the south wall. When the ledge rises up, open the poison sign and take a lift with health bonuses down. Follow the trail of health bonuses to get a soul sphere. (sector 443)
 * 5) Open the yellow door, then look to the left and shoot at the metal wall to reveal a switch. Jump there and flip it, then hop down and head southwest, going further that way to get a megaarmor, a chainsaw, and a stimpack. (sector 470)
