"DEF Island!" Game

You have an impressive cannon and an almost unlimited supply of ammunition, so feel free to shoot all enemies to provide the local population with protection and a peaceful life after you have dealt with all the enemies. You're not in a very good position - enemies are arriving on the island, they're coming up in boats and flying up in planes.
