Entering the Konami code will unlock the motor mouthed comedian turned MMA announcer Joe Rogan.
Xbox One:
Up, Up, Down, Down, Left, Right, Left, Right, B, A, Menu Button.
Playstation 4:
Up, Up, Down, Down, Left, Right, Left, Right, O, X, Options Button.
If you have entered the code correctly you will hear Rogan holloring 'Wow! I love it!' as confirmation and he can then be found in the Welterweight division. Rogan clocks a respectable 86 rating even though he has never stepped into the octagon before.
