QuakeWorld client/server

QuakeWorld is an Internet multi-player specific version of Quake. While the original version of Quake can be played over the Internet, many users modem users - the majority of players, had less than satisfactory play. Symptoms like excessive lag - actions actually happening much later than you did them; packet loss - the game would freeze and resume several seconds later; and various other difficulties plagued users. QuakeWorld is optimized for the average modem Internet player. It does only 1 thing, play deathmatch games over a TCP/IP network such as the Internet. It has no support for solo play, and you can't do anything with out connecting to a special server.
