For times when just one shotgun isnâ€™t enough, and you donâ€™t want to put forward the effort of actually carrying the thing around (they do get heavy you know), comes the Hammer H2X-40 Shotgun-Turret System. This thing is un-freaking-believable. Its got twin 20 round magazines, fires 3 inch shells, and can be used to fire â€œgrenadeâ€ rounds. Not too sure what those are, but they sound like a blast. All of this is controlled from inside your tank/SUV via a joystick, for that true first person shooter feel. Apparently designed for the military and civil defense groups, Iâ€™ll be checking eBay for one to pop up so I can play the ultimate live action duck hunt game.
