From last night's Kinect official unveiling, a new Star Wars game was announced. However, little is known about it other than you get to use force powers and lightsabers... oh! you get to battle Darth Vader as well! Rock on!
Kotaku has posted a 20 second clip (external link) showing off the demo and it looks epic.
The video opens with the player using a force power to knock away all the Stormtroopers. From there a space ship touches down in front of the player with Darth Vader stepping off and flicking on his lightsaber, and then the duel begins (and ends).
It is quick, but it was definitely neat to see it in action.
