User Summary: Bird Strike is a take on Space invaders in which the player controls a sideways-moving tank at the bottom of the screen. Aircraft come down out of the sky, and your job is primarily to destroy all 6 with a direct hit to the center of the aircraft. If the player shoots the planes off-center, then a carrier pigeon flies across the screen. Shooting this adds a note to a musical score at the top of the screen - completing this score also completes the level.
