GameSpot writes: "Inside the octagon, there really wasn't a lot wrong with UFC 2009 Undisputed, which makes it all the more impressive that the combat in UFC 2010 Undisputed is so much better. New features and improvements aren't confined to the cage, either. When you're not busy punching, pummeling, or posturing, you can create a custom fighter who's no longer restricted by styles, play through a far less clunky (though still problematic) Career mode, and shop for trading cards and unlockables using points earned in all-new modes. Some of the new features have come with problems, but despite some drawbacks, UFC 2010 Undisputed is definitely a bigger and better game than its predecessor. Its fighting system is deep, but it's also accessible enough that you don't need to be a fan of mixed martial arts to enjoy it".
