A listing has shown up on GameFly for a shooter called 'Heavy Fire: Afghanistan' which, judging by the cover art, requires Kinect. The synopsis on the official site of little-known publisher Mastiff Games doesn't give much away, reading like virtually any other modern shooter.
Given the publishers catalog of games, and the complete lack of media, our expectations aren't high for what could be Kinect's first traditional shooter. It's currently unknown how Kinect will be utilized and, although it is required on the Xbox 360, the game will be hitting "all major consoles and mobile platforms".
We won't have long to find out, the game launches April 30th.
