STAR WARS – The Force Unleashed Ultimate Sith Edition is a Collector's Edition that features downloadable content and 3 brand new exclusive levels – Jedi Academy, Tatooine and Hoth. In terms of additional content, players get an expansion of the base game. Each of the three additional levels is self-contained, so there is no need to beat the game to get to them. The downside to this is that none of the game's abilities or anything else carry over into them, nor do earned achievements carry over into the main gameplay.

Star Wars: The Force Unleashed Ultimate Sith Edition introduces unique levels. Jedi Academy is a bonus level where gamers must pass a kind of personal test. There's a small, simple puzzle towards the end that helps slow down the pace a bit. Tatooine levels up after the main game and is based on the premise that the protagonist kills Darth Vader and takes the position of apprentice under the Emperor. The Empire has learned that R2-D2 has plans for the Death Star, and Starkiller goes to talk to Jabba the Hutt. Once in his palace, the gamer will have to fight many enemies before going in search of droids in Mos Eisley.

The Hoth level involves passing through a series of square rooms and corridors in the base of the same name. Here you have to fight Luke Skywalker. The battle with him is much more difficult than with Boba Fett or Obi-Wan Kenobi in the previous mission. He has attacks that cannot be blocked.
