Play as a machine gunner defending your beach from an enemy invasion. Survive 10 waves and win the game. Each wave gets harder and harder. Don't allow more than 10 enemy soldiers make it to your defensive wall.
Your objective is to shoot the bad guys as accurately as possible. You can aim for the head or the body area. The closer you are to the center of each of these areas the more points you gain. The trick is to make every single shot count.
