Mystery Box Glitch!!!

Everybody should have heard of Nacht Der Untoten, or Night of the Undead. The Mystery Box in this Nazi Zombies has an interesting glitch. The two ? on the box go from white to gold I have no promises this will always work but When the ? shines brightest buy your gun just then and you will almost always get a good gun which will allow you to kill more zombies and ultimately survive longer.
