Good game! I would make the following suggestions: The Machine Gun is overpowering. Add an armor unit making the Machine Gun ineffective. Change the shotgun to a Bazooka and allow the Rifleman to be upgraded to an RPG at some point to be effective against armor. I can't wait to see the final version.
