Map of MAP33

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


  1. The starting sector is a secret which triggers immediately when the map starts. Impossible to miss. (sector 76)
  2. On the left-hand side of the map is a raised ledge with a blur sphere on it. You can reach it after the walls in the small rooms housing the mancubi lower, and you can then perform a running jump to the ledge and trigger the secret, but you can also reach it by hugging the grey brick wall, and then finding a suitable place to perform a running jump over to it. (sector 322)
  3. A similar secret is found on the other side of the map, though it houses armor. The same method(s) can be used to reach it. (sector 1237)
