There's a secret weapon to be found in the Mob of the Dead zombie map called the Golden Spork. In case you've been living under a rock for the past few weeks, Mob of the Dead is a new map for the Call of Duty: Black Ops 2's Zombies mode that was released with four other maps in the Uprising DLC.
As the name suggests, the Golden Spork is a spork made out of gold, but what it doesn't suggest is the fact that it's a one-hit-killer even past round 31—which is where the game becomes really difficult. Keep in mind that only a single player can acquire the weapon. There are some nasty and fun glitches in the game too, the guide for those can be found here.
MrDalekJD has prepared a guide on how to get the spoon, which you'll need to shock a number of times while in supernatural mode, effectively electrifying it. And then, well, just watch the video for the rest of the steps.
MrDalekJD has prepared a couple of other guides for the Pop Goes the Weasel easter egg, and one to help you achieve a 100% rating on the map.
