It's High Noon and you must shoot outlaws early during the levels to get a higher bonus at the end of a wave in duels. Keep moving around since outlaws will always shoot in your general direction. You can exit the screen to the left and right to reappear on the opposite side. Use this to your advantage to avoid bullets. From wave three onwards outlaws will throw dynamite sticks at you. Shoot the dynamite to kill outlaws. Horses wave 4 onwards can't kill you but the riders might. Enjoy playing this game here at Y8.com!
