Darkplaces

Darkplaces is a significantly modified and enhanced version of the id Tech 2 game engine. It features an OpenGL renderer, support for shaders, normal mapping, deluxemaps, bumpmapping, realtime lighting, bloom lighting, model interpolation, and many other effects and enhancements. Supported games include Quake, Nexuiz, Xonotic, and RetroBlazer.  
I'm pleased to announce that Darkplaces engine, Quake-HD-Remix (requires game data), Nexuiz, Xonotic, and RetroBlazer are now available in the Fienix software repository.
