Did you enjoy the first Assault Heroes on Xbox Live Arcade? If so, you'll be getting a sequel on May 14. It'll cost you 800 MS Points and now includes improved on-foot gameplay and hijackable enemy vehicles.
The first game was pretty awesome and rocks the top-down perspective like the classic games of old. It featured five levels and co-op play with tanks, on-foot gameplay, and mayhem. Check out the demo of the first on XBLA now!
