Recently, VG Leaks has found footage of the supposedly canceled RTS, Gears of War: Tactics . The game was supposed to be a game that you controlled with the Kinect, in order to allow you to move multiple units at once. The VG Leaks video is two minutes long and shows users using several different motion gestures to move your units and use special abilities. You would draw with your finger in mid-air to order your troops around, and then use several other different gestures to do things such as call in air strikes.
You can watch the full video leak here.
