The "Tatooine Mission Pack" for Star Wars: The Force Unleashed is available starting today for PS3 and Xbox 360. The mission re-imagines the Star Wars canon as if the "Secret Apprentice" had killed Vader and is on the hunt for Obi-Wan Kenobi on the sand planet. Players will also be able to check out Jabba's palace and "encounter" Boba Fett. We have absolutely no idea how long this mission pack is, so feel free to let us know in the comments. The pack is quite expensive at $10 (800).
What isn't available as DLC is an additional mission that takes place on Hoth and has the Apprentice seeking young Skywalker. That mission will only be available on the Ultimate Sith Edition of the game, which releases in early November. Instead of spending the cash now, it may be best to wait until the new game (currently listed for $40 on Amazon) comes out -- and get the aforementioned DLC packs and the Jedi Temple Mission Pack all on one disc.
