While you wait in our reviews of
UFC Undisputed 2010, you can try using Shaquille O'Neal as UFC fighter. Since he and the rest of the Cavs are taking the next couple months off after not reaching the Eastern Conference finals, you might as well use Shaq for something useful.
The code is seen on
MiddleEasy.com and you can get to use him by this:
Xbox 360: At main menu - Down Up Left Down Down Left Up Down Down Left X Y Y X Start
PS3: Down Up Left Down Down Left Up Down Down Left Square Triangle Triangle Square Start
Now go do some
Shaq-Fu on the other UFC combatants.
