Unreal Tournament 3 (UT3) is a first-person shooter and online multiplayer video game by Epic Games, and is the latest installment of the Unreal series. It is published by Midway Games, and was released for Microsoft Windows on November 19, 2007, PlayStation 3 on December 11, 2007, and Xbox 360 on July 3, 2008. The Linux and Mac OS X versions of the game were planned to be released as downloadable installers that work with the retail disc. Ryan C. Gordon has uploaded screenshots of the game, dating from September 2008, running on both platforms. On May 22, 2009, Ryan stated that the UT3 port for Linux was still in process. On December 16, 2010, Steve Polge announced that the Linux port would never be released, making it the first Unreal Tournament game not to be released on Linux.
Unreal Tournament 3 is the fourth game in the Unreal Tournament series and the eighth Unreal game, but is numbered in terms of the engine it runs on. The original Unreal Tournament uses the first Unreal Engine, while UT2003 and UT2004 use Unreal Engine 2. Since 2004 incorporates all of the content from 2003, they are regarded as part of the same generation. UT3 is the third generation, as it runs on Unreal Engine 3, and does not reuse any content. In March 2008, Midway announced that UT3 had sold over a million copies worldwide.
On May 8, 2014, Epic Games announced a new, free and crowdsourced Unreal Tournament title.
Similar to the prior entries of the series, the game is primarily an online multiplayer title offering several game modes, including large-scale Warfare, Capture-the-Flag, and Death match. It also includes an extensive offline multi-player game with an in-depth story, beginning with a simple tournament ladder and including team members with unique personalities.
