The Challenge ProMode project was created by Richard "Hoony" Sandlant in May 1999, following the release of Q3Test, the beta version of Quake III Arena.
On August 28, 2000 the final version, 1.0, was released which was followed in December 2000 by the project changing its name to Challenge ProMode Arena to reflected the added multi-arena capability as Kevin "arQon" Blenkinsopp became the lead programmer.
