PumpAction provides a fun, pump action shotgun simulation. Launch the application and hold your iPhone or iPodTouch upright in your hand. Rapidly move you hand in a up and down motion simulating the pump action of a shotgun. You’ll hear the pump action sound, which tells you that a round has been chambered. Touch the screen to fire the round. If you touch the screen with two or more fingers, it will fire off two rounds. If no round is chambered, touching the screen will result in an empty chamber click sound
