When Mass Effect 3 hits the Xbox 360 it will feature Kinect-based controls. Bioware released this video to show the Kinect controls in real time. Some of them are gesture controls and other parts of it deal with voice commands that players can use.
For example, to switch weapons players say the name of the item that they want to use. So, you could say, “Sub-Machine Gun” and Shepard will pull out the gun.
Mass Effect 3 will be out on March 6. The game will also be available on Playstation 3 and PC but, of course, lacking the Kinect control system.
