Walkthrough

Map of Unknown

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. As you flip a series of switches to open up the north teleporter in the first area, one of those switches will be just north of where the blue key is. After flipping that switch, return to the starting point and you can find a BFG9000 and energy cells. (sector 74)
2. In the southeast caves, head to the southeasternmost part and use the wall between the two torches to find a soul sphere. (sector 117)
