The Ultimate Sith Edition of the game will be released as a special edition of the game to be released this holiday season. It will feature the currently available DLC as well as two new levels. In addition to the original game, the Sith Edition will continue the game where one of the endings left off. Warning: spoilers ahead.
The two new levels, set on Tatooine and Hoth, pick up where the dark side ending of the game left off with the Apprentice serving the Emperor. The levels will pit Starkiller against familiar faces such as Obi-Wan on Tatooine, Luke on Hoth, and Boba Fett at Jabba’s Palace. Both levels will also be available as downloadable content.
