Cannon Turret Bobblehead PS VR PS4 is a neat way to improve the look of your Cobra tank in Battlezone. With it, you can personalise your tank's command deck with a miniature "bobblehead" cannon turret. It serves no gameplay function and is intended purely for aesthetic effect, but it will look good standing inside your virtual tank. You will have plenty of fun watching it wobble and bobble away as the action gets intense.
