UFC Undisputed 2009 is easily the deepest UFC video game ever. The ground game is one of the most exciting features if done right. Of course you can sit there and simply ground and pound someone in 10 seconds but you have to be careful because the person on the bottom could catch you in an armbar as well. The movement is easy and the new muay-thai clinch system is also very good. We did feel that punching was a little difficult as the fighter's reaches did feel a little awkward but kicks are spot on. THQ did a great job of displaying each fighter's strengths such as Chuck Liddell's superior striking power as opposed to a guy like Lyoto Machida, who doesn't have the same power as "The Iceman".
