Walkthrough

Map of Pure Blood

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.

Essentials

Grab the megasphere (invulnerability on Hey, Not Too Rough or lower) and enter the arena. As the cyberdemon attacks you, use the north switch, then the south switch, then the east switch to release him from his pen. Do this quickly, as the outer ring of the level has a crushing ceiling coming down and you will want to avoid it by releasing the cyberdemon and trapping him there while entering his pen. You will have to wait for the crusher to come down a second time as the cyberdemon will survive the initial crushing. Make sure that when the crusher comes down, the cyberdemon is not in the central safe zone, which can be tough as you are trying to avoid damage. When the cyberdemon succumbs to the crusher a second time, get on the rising and lowering lift at the west end and ride it to the exit.

Secrets

1. The sector you start in is a secret and is impossible to miss. (sector 2)
