A sheriff must defend his town against outlaws, who are about to abduct women from "Saucy Sue's Saloon" or rob the local bank. To defend it, the sheriff is equipped with his gun, which is used to shoot one of the outlaws. Shooting can be done in a horizontal, vertical, or diagonal direction. There are five waves to complete, and the outlaws get tougher after each level, with outlaws riding horses, blowing up sticks of dynamite, and hiding behind windows. In Wave 5, the sheriff is out of town and finds himself outside the entrance of the cave where outlaws emerge from.
In Waves 1 through 4, when an outlaw is killed, the undertaker will come out from Rig + Mortis Undertakers and collects any bodies found lying around. After each wave, there is a bonus duel between the sheriff and the outlaw. The sheriff must quickly open fire before the outlaw.
