This edition of the game includes both the two downloadable levels available from the Xbox Marketplace, plus the addition of a new level based in the Hoth system. The new content is presented on a separate disc, which means that the new stuff isn't fully integrated into the old game. This may be frustrating for those who have purchased the game already. I would really only recommend this version to true fans of the series, as there is only variation in terms of unofficial story, no gameplay additions etc. Yet, as I felt the original version was already a master piece, this package comes as a welcome treat for us who crave more of Starkiller and his new status as Sith Lord.
