22 minutes of gameplay [Edit: this covers almost the first hour of game, though cut up into pieces as to explain a few key features of the game mechanics]. Made by the arcade team behind the House of The Dead series [not including Overkill as that was done with a different team.] Also commentated and helps explain the control style of the game. Not sure if this vid also explains the difficulty they ran into with mapping gestures so I'll post that vid once I find it again, very interesting viewpoints in regard to the kinect in Japan and the US.
All I have to say is 'Finally, another game other than Child of Eden and Steel Battalion that makes it worth owning a Kinect'. The people behind the game know this, and constantly bash the shovelware dancing games and the like during commercials for the game. Very Family Unfriendly. Can't stress this enough, though the part that comes to mind isn't shown in this video, it gets pretty weird later on [think dog, and that may as well be the tamest part of the game]
Looks pretty interesting. The kinect is a lot like the Wii when it first came out, all the family games and shit, but as time went, the good games atarted coming in. Got me a Dead Space game for the Wii, not so family any more, huh?
