It’s true, Shaq is in the UFC Undisputed 2010 game as an unlockable character as you see above, as he fights against the late Mask of Tapout. Even better news is that you can start beating down guys with Shaq, Tapout crew or bizarro world Penn right from the beginning. Simply type this code in at the start screen.
Shaq – down, up, left, down, down, left, up, down, down, left, X, Y, Y, X, start
BJ (Black Trunks) – LB, RB, LT, LT, RT, RB, LB, Y, X, X, Y, start
Tapout guys – down, down, up, down, left, down, select, start
