you try to shoot as high scores as you can. It is a black sky with stars shining. You are a blue battle plan which has 4 lives at first. The blue flies line up and stay the half sky for a long time. The red ones will fly like a circle and they will line up on top of the blue ones. And they will drop bullets when they fly or fall down. There is always a red dragonfly with yellow wings flying from one side to another and it can also drop bullets too. What you do is to shoot all the fliers off and don?t let them fall on you or hit by the bullets they drop. Have fun!
