Secrets

 * 1) At the southernmost nukage area, head northwest to a small room and jump southwest out of the small window. You should land on a small ledge. Open the wall where the ledge is and follow the corridor to the courtyard, where you will find shotgun shells, partial invisibility, and health bonuses. (sector 15)
 * 2) Jump into the nukage where the yellow key is and head left. The room you find has health bonuses, armor bonuses, a stimpack, and a backpack. (sector 125)
 * 3) In the hall at the south end with a computer terminal at the east side, get on the terminal and find a switch at the southwest end. Use it, then quickly run down the hall and east into the next room. Get on the lift and ride it up to get a rocket, a megaarmor, and a rocket launcher. (sector 167)
 * 4) Take the lift down to the room with the switch that raises a switch in the yellow key room. While the lift is down, open the northeast corner wall and flip the right switch. Take the lift back up, head off, then take the east door. In the next room, open the west door and you can get the soul sphere in the middle of the nukage there. (sector 175)
