From the feature PlanetXbox360.com review:
"Last year gamers and MMA fans everywhere were ecstatic to finally get a big-budget fighting game involving the Ultimate Fighting Championship, from mega-publisher THQ and developer Yuke’s (studio behind the past couple WWE video games). The UFC Undisputed series was off to a good start, and the 2010 edition is the sophomore attempt at bringing realistic UFC gaming to the Xbox 360. UFC Undisputed 2010 takes everything the game learned in it’s first outing and improves on it, including a ton of more fighters and extra things to spend time doing. UFC is still in a growing stage and fans of the sport are hardcore, wanting each and everything about the UFC game to be perfect (or at least very accurate). We went into the review of Undisputed 2010 with this mindset, looking at all of the features from the perspective of the ultimate UFC fan."
