A Google Cache page has revealed the existence of Fighter Within, an Xbox One Kinect powered title from Ubisoft.
The game's description reads:
"Discover Fighter Within, the next-gen game that provides you the excitement of a real fight, throwing you into the most immersive total-body combat experience ever made. Enter a world of sweat, timing and training thanks to kick-ass motion recognition. Brawling with your friends will never feel the same again.
"Test your real fighting skills thanks to the next gen of motion recognition. The new Kinect technology arms Fighter Within with realistic fighting moves using unprecedented 1 to 1 precision movement tracking.
"Enter a brutal, physical and liberating world. New-gen jaw-dropping graphics, real-time wounds, sweat & facial impacts, extreme arenas environments, primal animations… The new Xbox One Kinect allows you to dive into a unique realistic experience and feel the fight. All you expect from a next gen fighting game is there."
The game is likely a sequel of sorts to Xbox 360 title Fighers Uncaged and is said to be "Coming Soon". However, Ubisoft has not yet revealed the game so quite if or when FIghter Within will be released is unknown. It's possible more will be revealed about the game at gamescom this week.
Fighters Uncaged was widely panned for bad AI and poor Kinect integration.
