Earth is being invaded by aliens known as "The Creeps." You are manning a turret to eliminate as many creeps as you can. Move the crosshairs over a creep and click to destroy it. There are 5 different creeps: Greys, who are normal; Reds, who are very fast; Yellows, who put up a force field, shoot them when the shield is down; Blues, who cause instant death if not shot; and Greens, who become invisible.
