Unlocking Bonus Levels
Star Wars III: Revenge of the Sith has several extras that can be accessed when you complete levels on the game or make special achievements. By inserting special codes you can unlock the extras without having to play the game. Codes can be entered by choosing "Settings" on the main menu and selecting "Codes."
Revenge of the Sith has five bonus levels that are not a part of the main storyline of the game. The bonus levels are shorter than the regular levels, and often have different game-play elements than the rest of the game. For example, in one level you get to play as Yoda, a character that is not available in any other part of the game. You can even reenact the classic battle scene between Darth Vader and an older Obi-Wan Kenobi on the Death Star. To unlock all of the bonus stages in the game, enter "NARSHADDAA."
Unlocking Dual Arenas and Duelists
In addition to the story mode of Star Wars III: Revenge of the Sith, there is a dueling mode, where you can enter a battle against a character from the game that is controlled by the computer or by another player. The characters and dueling arenas are normally made available by advancing through the game.
To unlock all of the duelists, enter "ZABRAK." Enter "TANTIVEIV" to unlock all of the dueling arenas.
Obi-Wan Kenobi Death
One of the most memorable scenes from the first Star Wars movie is Obi-Wan Kenobi's death at the hands of Darth Vader. In the scene, Kenobi raises his lightsaber to his face and allows Darth Vader strike him down. You can recreate this act in the dueling mode of the game. To recreate the act, choose Ben Kenobi as your character in dueling mode. When the duel starts, press "L1," the "Square" button and the "Circle" button simultaneously. Kenobi will raise his lightsaber in front of his face and disappear when your enemy strikes you, just as in the first Star Wars movie.
