OpenNI and Unity, the demo features a lone survivor fighting off hordes of zombies with a pair of pistols. Both hands aim independently and, honestly, the demo has given us a better appreciation of the difficulty inherent in dual-wielding (Lara always made it look so easy!).
Pixel Ninja will release a downloadable version of the Zombie Holdout Kinect demo on March 7 for PC. In the meantime, you can catch a video of it in action after the break.
