Wolf-Stone is a Blake Stone: Aliens of Gold mod which brings the levels from Wolfenstein 3D into the Blake Stone game. Levels have been ported directly from Wolfenstein 3D into Blake Stone with minimal editing, in an effort to see how the engine interprets the differing art asset markers. The only changes made are when elevator (your level exit) doors wouldn’t open, or keys needed were not included within the levels by default (the engine often interpreted these as a ceiling light). The mod is a work in progress, and only the first two levels work at this time.
Mod can be found on GitHub.
