It's all well and good to have this impressive tech, but what of the games. We've seen how a driving game could work, but how would something like a first-person shooter shape up using Natal? Kudo, obviously well rehearsed on the subject of the FPS, explained how you might one day be shooting down aliens using nothing but your body. For starters you'd position your arms and hands as if holding a gun and you'd aim by pointing the imaginary gun. To move forward you move the gun towards the screen, bring it back to move back. Likewise, moving the gun to either side would strafe. Jump by jumping, knife an enemy by making a slashing motion, throw a grenade by... well, you've got the idea. And what about firing your gun? Use the trigger finger, of course. It's too early to know if this will work when put into practice, but the possibility is certainly there.
