Once you have completed the Easter egg, every time you kill George A. The Wunderwaffe DG-2 can also be obtained in the map Call of The Dead though a Power-Up and not the Mystery box which makes it free, however the player must complete the map's Easter egg which some items cost to complete the Easter egg. The Black Ops version of the Wunderwaffe DG-2 is exactly the same as the one from World at War, except the appearance is slightly different, otherwise stats remain the same. Also there is a glitch were hurting your self with the Wunderwaffe DG-2 will stop the effects of Juggernog working even though the Juggernog icon will still be in the corner it will be inactive (this does not happen in the Black Ops version).
This weapon is very useful for getting rid of hordes of zombies close together, however it is not so good for up close combat as it can damage the player making it easier for zombies to kill the player when hurt by the weapon. The Wunderwaffe DG-2 is one of the most powerful none Pack-a-Punched weapons in the game as it can kill up to 10 zombies with one shot.
