Walkthrough

Map of Waste Refinery

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

1. Open the red doors, use the lift, and open the door to a switch. You can open one of the walls south of the switch to get a chainsaw. (sector 147)
2. Open the southwest door in the large area at the northwest end. When the hall bends west, open the south wall to get a rocket launcher. (sector 149)
3. At the northeast area, open the west wall to find two terminal blocks. Use the south one from the south side and you will see an arrow pointing north. Go that way, stepping on the block and the next one, to open the north wall with a computer area map and partial invisibility. (sector 320)
