You don't need controllers to use Microsoft's Xbox 360 Kinect. That's the point of the thing. You don't need a controller. You certainly don't need an inflatable boat. But to play the upcoming Cabela's Big Game Hunter: Hunting Party, you're going to need a special Kinect gun. It comes bundled with the game.
How does the Kinect track your limbs if you're holding the thing? Well, it tracks the lights of the gun — and your legs as you kick at wolves.
