I just recently acquired a MISB Universe Hardhead. After testing the figure through the "try me" window, I think the one I have may be defective. I thought that when you press and hold the button on top of the turret the first time you'll hear a continuous siren. Press and hold it a second time and you get continuous machine gun noises. Am I right about this? When you press and hold the turret button on the one I have, all you hear is the continuous siren no matter how many times you press it. No machine gun noises whatsoever. Is this one defective? if so, can it be repaired? Has this problem been reported before? Is it common? THANK YOU to anyone who posts!!
