Play As Devil Kazuya Cheats

Play As Heihachi:
To play as Heihachi you must beat the entire game without continuing.

Play As Sub-Boss:
First beat all the normal characters in the game. After beating all the characters you will have to fight your character's sub-boss. After beating that sub-boss you will be able to play it as a normal character

Play Galaga With Two Ships:
During power-up, press and hold Up+L1+Triangle+X on the player two controller.

Play Galaga continuously:
Press select after it shows you the kill number and you should hear a "ding" noise. Instead of skipping to the intro Tekken screen, it will go back to the same Galaga level you were on.
