3. In the central area, enter the north building and open the red door. Use the southeast terminal and leave the building. Head south to get a chaingun. (sector 58)
4. In the room maze at the south end, go to the southernmost end and open the west door. Use the south terminal, then head east, north, and east. Shoot the south wall and take the lift up, then follow the path to a green armor. (sector 210)
5. In the blue room west of the room maze, open the southeast wall, head south, and use the switch to access a new hall. Press the switch here to open walls to the north. Head back to the blue room and open the east door, then head north to get a computer area map. (sector 80)
6. Open the northeast wall in Secret #5 and get an energy cell. Open the door and shoot the barrels to get stimpacks. (sector 82)
7. In the spider mastermind room, head to the northeast ledge and flip the switch there. Head to the south end and into a new hall, then enter the room.
