Walkthrough

Map of Constriction

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. At the east end of the map, fall into the blood at the south end and use the lift. Go through to get armor bonuses, a berserk pack, and a chainsaw. (sector 61)

Bugs

When the north part of the east walkway is walked across, a wall lowers to release an ambush. Some gore (thing 163) is placed on this wall but fails to lower, making it appear to float in the air. This is caused by the corresponding mobj bearing the MF_NOBLOCKMAP flag.
