I like this game, therefore i've made a 5 star review in U.S. AppStore @speed4mee:
Great Defender - Shooter!
Very well designed comic style game with a unique mixture from shooter and defender. The gameplay and the fitting sound are flawlessly.
Your goal is, to defend your terrain. You must aim and then shoot with your cannons, to kill the various aliens. Helpfull is the shown aiming line. You can unlock various cannons and the aliens have different properties and therefore it is a very challenging game, that makes a lot of fun.
Game Center and OpenFeint is integrated, both with several achievements, that's very good.
Thank you for this unique game!
