Unreal Tournament 2004

Unreal Tournament 2004, also known as UT2K4 and UT2004, is a futuristic first-person shooter computer game developed by Epic Games and Digital Extremes. It is part of the Unreal series of games, particularly the subseries started by the original Unreal Tournament, and is a sequel/expansion to 2002's Unreal Tournament 2003.

The game features most of the content of its predecessor, replacing it on the shop shelves. Unreal Tournament 2004 boxes sold in the United States include a $10 mail-in rebate requiring that a short form be completed and sent to the publisher along with a copy of the manual cover for Unreal Tournament 2003. Versions sold in the United Kingdom had a similar offer, but required sending in the play CD for Unreal Tournament 2003 instead.

Among significant changes to gameplay mechanics and visual presentation, one of the major additions introduced by Unreal Tournament 2004 is the inclusion of vehicles and the Onslaught game type, allowing for large-scale battles.

Its sequel, Unreal Tournament 3, was released on 19 November 2007.
