Star Wars Episode III: Revenge of the Sith Cheats

When in a duel select Ben Kenobi. In the duel press and hold block(L1), square and circle. He will bring his lightsaber up to his face like in episode IV. If you want to get killed you only have about a second to get hit. If you are hit the right way Ben will disappear (ala A New Hope).If you are hit a different way like a grapple you just die. It is really cool if you play in the death star arena and your opponent is Darth Vader

Once you have completed the game, go back to mission #17, Revenge of the Sith. You will play as Anakin instead of Obi-Wan. If you defeat Obi-Wan you get to watch an alternate ending.
