Gloom: 3 Open Source Clones Compared
GloomAmiga is the original developer's own released source code for the Amiga FPS, provided as-is with no guarantee it's complete or final. ZGloom is a separate, from-scratch reimplementation for Windows and Linux that requires the original Gloom game files to run and has documented gaps versus the original: Z-fighting rendering artifacts, no defender sub-game, and occasionally overly loud audio.
