IGN reports that the Xbox 360 version of UT3 will have five new "exclusive" maps, two new characters and includes two-player splitscreen. It will also contain the free maps available as DLC for the PS3 and PC versions of the game.
Jeff Morris, senior producer at Epic, tells the site he believes UT3 will be a reprieve for those with "tactical shooter fatigue." He stands by the game being an "unabashedly twitch" title. We're expecting more details (maybe even a release date) on the Xbox 360 version of UT3 sometime tomorrow.
