Today’s the day. UFC Undisputed 2010 is now in stores across the US. If you’re still on the fence about picking up this year’s copy, IGN has a honest review of the game. In short, it’s an improvement over last year’s debut title, but it’s not perfect. They gave it a “Good” 7.8/10.

Oh, and if you haven’t figured it from the picture yet, Shaquille O’Neal finally got his wish to be in the UFC.  He’s an unlockable character in the game along with the Tapout crew. Check out MiddleEasy for the unlock codes.
