Doom Legacy is an enhanced version of Doom with 3D OpenGL graphics.
We don’t want to create another Doom-clone with the sources. First, we’ll bring a lot of bug-fixes – updates – features that should have been in Doom since the beginning. Then, we’ll try to ‘refresh’ Doom’s visual aspects so that it looks better on today’s machines. And last but not least, we will extend the engine with enhancements for map and ‘mods’ creation.
Pros: Doom Legacy is a fun time-wasting game. I can’t explain it any further. Doom Legacy is a cross-platform game for Mac, Windows, Linux, DOS, and OpenBSD.
Cons: The Mac port of Doom Legacy exhibits a few minor graphical glitches.
