Star Wars: The Force Unleashed received new DLC this morning! The Tatooine DLC is 800 and comes in at 837 MB. Xbox 360 gamers can purchase the DLC on the Xbox.com Marketplace right now, but PlayStation 3 owners will have to wait until the PlayStation Store update later today.
The third piece of DLC, Hoth, is only available if you purchase the upcoming Star Wars: The Force Unleashed: Ultimate Sith Edition. There are no additional achievements or trophies however, so renting the game is always an option.
