【實用動作app】The Alien Fight|最夯免費app-gigacircle

This app is a simple XNA based game developed for WP7. The concept goes like this- you are a tank firing 4 bullets (on an avg) and the tank can be controlled by you(touch it to move) and the bullets follow the tank. There are a number of enemies passing randomly and some of them emit bullets. You're given 4 lives to remain away from those emitted bullets and make a new score!
