The UFC series took a little break from the annual release cycle and all that extra time was spent creating a more robust sequel. Undisputed 3 introduces a ton of new content, including the new Pride mode where the Japanese MMA fighting style allows for brutal attacks like kicks straight to the head.
Other additions to UFC 3 include a new submission system, fighter entrances, new camera positions, and a revamped online experience. You can also expect a simplified control scheme on top of the traditional controls that allow newcomers to get a better grasp of the game.
The final major point you should know is that there are over 150 UFC fighters to play as in addition to the new Featherweight and Batamweight divisions.
UFC Undisputed 3 will be out early 2012 for the Xbox 360 and PlayStation 3.
