The name, design and how to use is very similar to the Wunderwaffe DG-2. Major differences include a Sniper Scope, a higher ammo capacity, a mag-fed reload, and a slightly lower range, necessitating zombies to be closer together in order to score chain kills. Its power is amplified when landing headshots on zombies, killing faster as well as having bigger chain effect for killing more zombies. The weapon can be obtained from the Mystery Box for 950 points, or for free as part of the main quest.
Once upgraded, the weapon becomes the Wunderwaffe DG-Funkenschütze.
