ProQuake

ProQuake is a modified Quake engine, developed by J. P. Grossman from the original id Software GPL-licensed Quake code. ProQuake was created to further competitive play, including features such as more granular aim and cheat-free mode. Its stated goals are to provide improvements and fixes without changing the nature of competitive game play. ProQuake is fully backwards-compatible to original Quake (NetQuake, not QuakeWorld). The last version released by J.P. Grossman is 3.50, and it was released on September 21, 2002.

In early 2008, a new project emerged under the name "Proquake 4" to continue development. The latest version of that release is 3.99s, and it was released on March 6th, 2008. [http://www.quakeone.com/proquake/]
