Walkthrough

Map of Nessus for the Master Levels for Doom II

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

Secrets

  1. The map contains one single secret, which is inaccessible due to a logical error in design. The sector flag 9, marking a secret sector, is placed in the "doorway" step leading up to the actual secret sector. The player will always step over the marked sector and thus the secret is never triggered. (sector 211)

Bugs

See above. The bug in question is well known, but no fixes are forthcoming.
