The sequel to the original Unreal Tournament from 1999. According to Wikipedia this game set a record in number of downloads when the demo-version was released. The Unreal Tournament 2003 engine has been used for several games such as Rainbow Six, Splinter Cell and America's Army.

Unreal Tournament 2003 requires a Pentium III or Athlon running at 733MHz (700 ~ 750MHz Athlon). As graphics card a 16MB DirectX8 compatible card is required but faster cards like the Radeon or GeForce 2 are recommended. For fluid gameplay a faster card is no luxury.
