There's a GameGun Update video on the YouTube offering another look at this first-person shooter peripheral first revealed a couple of months ago. The clip shows more of the Game Gun in action, which features a gun-mounted screen for full motion tracking, and announces Windows will be one of the supported platforms along with consoles. They say preorders begin soon, and that the Game Gun should be ready for Christmas, though details about pricing are not being discussed yet. Thanks Mike Martinez and Engadget.
