Secrets

1. Take the east lift at the center, then head south and then west to the rocket launcher. Open the north wall to get stimpacks, rockets, and partial invisibility. (sector 89)
2. Take the west lift at the center, then head north and east. Go down the steps and use the wall with the white light to find a teleporter to a soul sphere. (sector 183)
3. At the yellow key, head to the north block and go behind it. Flip the switch to lower the chainsaw. (sector 281)
