Massive pack of enhancements for the Darkplaces engine running Quake. From the site: Quake Epsilon is a graphically enhanced build of shareware Quake 1 for Windows/Linux/Mac, which can be upgraded to the full version of Quake along with it's mission packs Scourge of Armagon and Dissolution of Eternity by copying the full-version .pak files into the correct folders. It's made out of the Darkplaces engine and many mods from members of the Quake One forums and elsewhere as well as my own work.
