LucasArts unveiled their mystery Star Wars game tonight at the 2009 Spike VGAs. As you may have guessed, it's a sequel to Star Wars: The Force Unleashed.

A brief trailer begins with TFU protagonist Starkiller walking down a corridor, while dueling voiceovers of Yoda and Vader play. It suggests that once again Starkiller will be faced with the temptations of the Dark Side. He exits the corridor into a giant arena, where he fights a huge beastie. Seems he's graduated from fighting rancors.

The platforms weren't announced. Its official website is called Unleashed2010.com though so expect it next year.
