Project Unity is a 3d engine that trys to incorperate the good systems of RTCW with realistic physics. The project started in 2004 around June.
Unity`s current goal is to emulate RTCW as closly as possible and to make the engine have as realistic physics as possible.
The next step being to create a new game. Project Unity can currently render levels from RTCW, Quake 3, Elite Force, Jedi Knight 2 + 3 and Soldier Of Fortune 2.
The following peoples work,tutorials,units,etc have made Unity possible:
