The visuals and sound are top-notch and the gameplay is simply outstanding. The games tutorial mode shows you everything you need to know about MMA fighting in the virtual world and Undisputed's career mode features the best single player progression system I have experienced since EA Sports Fight Night Round 3. UFC fans and any next generation-console owners who enjoy a good fighting game should not hesitate to pick-up UFC 09: Undisputed. As for the casual gamer, you should give this game a try too".
