The game contains a bonus mission that lets you control Anakin during the epic duel with Obi-Wan Kenobi. If you manage to beat him, you are treated to a cutscene of Anakin betraying Palpatine and becoming the Emperor!
The game features many things that were cut from the movie, such as Clone Assassins.
