The mafia war has begun. You have to protect your territory against the enemy gang that tries to take over. Bring your armed men to the roofs to shoot and destroy every outsider moving in on your turf.
To Protect the Earth from alien invasion, you're given a ship class AT-021. But unfortunately the Earth doesn't have enough resources to supply new arms to the ship. Improve the ship by collecting weapons through battles and buy turrets to defend.
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.
