This is very simply Space Invaders recreated for Android, based heavily on the Nintendo 64 version of the game. Tilt your device for steering. Fire cannon by tapping (lower) right side of screen and fire special weapon by tapping (lower) left side of screen. NOTE: this is a rather short game! Source code for game is available at http://code.google.com/p/androidinvaders/. New developers and modifications are welcome.
