Rail shooters found Kinect a tenuously appropriate vehicle when Child of Eden hit the psychedelic sweet spot in June 2011. Now, charm-smothered and bristling with the potential of Microsoft's motion camera peripheral, The Gunstringer wrangles the awkward approximation of controller-free gaming with equally adolescent grace. It revels in referential nods and disgust for the fourth wall, burning sacred cows with gleeful frequency. It's imperfect and sensitive as Kinect gamers might expect, and it's relatively short. But it's a pleasantly unexpected justification for that expensive camera on the T.V. stand.
