Awhile ago we heard about the new Steel Battalion game being made for kinect and were left with a lot of questions regarding the gameplay. Well they have some news on this now and it sounds like they really made the right decisions. Keep the xbox controller for traditional movement of the mech and use the kinect to allow control of the interactive cockpit+head tracking.
