Steel Battalion: Heavy Armor is about as ‘core’ as you’re likely to see on Kinect. It’s a mech battle game that’s kind of like tank warfare. You use Kinect to control the inside of your mech and the controller to move your vehicle (are they vehicles, technically?).
It looks pretty fancy in this trailer but I can’t help wondering how many people will drop controllers when doing the flappy-arms bit. Still, it’s something other than dancing, right?
