Jason Miller/US PresswireBust out your own Shaq Fu in "UFC Undisputed 2010."

Shaq versus Brock Lesnar?

That's right, Shaquille O'Neal is hitting the octagon, at least virtually, as THQ made the man nicknamed everything from "The Big Aristotle" to "Dr. Shaq" a hidden character in "UFC Undisputed 2010."

And while there are a bunch of bogus codes floating around the Web, I called THQ and got the real code on how to unlock Shaq on the 360 (and I verified it on my own system).

To unlock Shaq, go to the main menu and press Right, Up, Left, Right, Down, Left, Up, Right, Down, Left, X, Y, Y, X, Start.

When the code is entered correctly, a message will pop up on screen telling you have unlocked a new fighter. Then head into an Exhibition bout and you will find Shaq among the heavyweight contenders.

Win a fight and you'll even hear Mike Goldberg yell: "Shaq Diesel with the victory!"

And with an 83 strength rating in the game, Shaq can throw some vicious elbows and uppercuts.

I guess now we finally know what Shaq Fu is all about.
