The Ultimate Sith Edition expands the story of Star Wars: The Force Unleashed and re-imagines the Star Wars Saga as if the Secret Apprentice had killed Darth Vader and taken his place by The Emperor's side, becoming the most powerful Sith Lord in the universe. In the Ultimate Sith Edition, the Emperor sends his new apprentice to the planet Tatooine to dispatch Obi-Wan Kenobi, who has been hiding on the planet ever since the events of Star Wars: Episode III Revenge of the Sith. During their hunt for the reclusive Jedi, players will also explore the depths of Jabba the Hutt's palace and encounter notorious bounty hunter Boba Fett. In the game's thrilling finale, the Secret Apprentice is sent to the planet Hoth on a crusade to crush the Rebellion once and for all. While on Hoth, players face Luke Skywalker himself while visiting iconic locations seen in Star Wars: Episode V The Empire Strikes Back. The Secret Apprentice doesn't just defeat his enemies with the Force- he hurls them through walls, smashes them into objects, shocks them with lightning, and even transforms them into Force-charged bombs capable of massive destruction.
