Thanks to the Twitter user superannuation we have details for an unannounced Kinect game from Ubisoft called PowerUP Heroes.
The game sees you turn your Xbox Live Avatar into a superhero in a fighting game that uses your whole body and voice to control various power suits. The game also features 2 player co-op with online battles.
Here's all of the details found on the Ubisoft store site:
The universe is in peril—and it’s up to you and your Xbox 360 avatar to eradicate the forces of evil. PowerUP Heroes is an explosive, super power infused, full body fighting game for Kinect. Take your Xbox360 avatar and power it up into a superhero and face off against ballistic super villains. Obliterate your enemy and seize their super suit and abilities to use in your next battle! Use the Necromancer suit and control a horde of skeletons or slip on the Mentalist suit to break into your enemy’s mind and much more!
