Walkthrough

Map of Circle Jerk

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. Collect the invulnerability (near the teleporter in the east), then head along the western corridor. Shooting the wall here opens it, revealing a teleporter. Go through the teleporter to reach a room with many items as well as an exit which takes you back to this level. Note that teleporting will explode many barrels, which will kill you if you are not invulnerable. (sector 57)
