The Force Unleashed On PC, Parallel Story

Third-person Jedi action of Star Wars The Force Unleashed: Ultimate Sith Edition will be turning up on the PC in the Autumn, according to Lucasarts. The PC game is an expanded version of the original Force Unleashed game, with three extra single-player missions. Bizarrely, the new missions set up a parallel timeline within the Star Wars universe, in which the events of the original films play out differently, according the events of the game. The second new mission in this rebooted version of the game "re-imagines the Star Wars Saga as if the Secret Apprentice had taken Darth Vader’s place at the Emperor’s side, becoming the most powerful Sith Lord in the universe. The story picks up as the Emperor sends his new apprentice to 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."

The final new mission apparently sees you facing Luke Skywalker in the assault on Hoth, via a quick visit to Tatoonie, natch.
