31-79 JGb215

The  is a new Wonder Weapon that appears in the most recent Zombies map, Shangri-La, which is included in the Annihilation DLC. It appears to cause zombies to shrink, having big heads but small bodies. Once they are shrunk the player can run into them to kick them and send them flying and killing them. Otherwise, small zombies can be killed with one shot. The shrink effects wear off after a few seconds.

When Pack-a-Punched, the weapon becomes "The Fractalizer". It has increased ammunition and the effect on the zombies lasts longer.
