This is the mother of all Things SuperDuper Quake. Included is two versions, 2.3 with bots, runes, mechs, and version 3 with no mechs or runes, but a few extra guns and lots of good clean code!
This is the Cheapy's Server-side Quake patch v0.7b Quake Expo 2003 edition, based on Quake v1.01 QC source code. NOTE: Your server's clients do not need to download anything when playing this:D
