See the following story posted over on GameSpot.com that provides an overview of the new Tatooine level that will be available this Fall as downloadable content for Star Wars: The Force Unleashed.
"With the one-year anniversary of Star Wars: The Force Unleashed looming on the not-too-distant horizon, LucasArts has been hard at work on new downloadable content for fans hoping to squeeze a few more adventures (and perhaps some Jawa punting) out of the Sith apprentice. When this DLC arrives, you'll once again take control of Darth Vader's soft-spoken underling as he travels to a pair of worlds near and dear to fans of the original trilogy: Tatooine and Hoth. We recently played through the Tatooine half of the storyline to see what you can expect when this content arrives in the fall."
WARNING: If you want to remain spoiler-free until the Fall when the DLC is released, then do not proceed past this Imperial checkpoint!
