Blundergat

The Blundergat is a new Wonder Weapon featured in the Call of Duty: Black Ops II zombies map Mob of the Dead. It is based on civil war-era weaponry, consisting of ideas from the both the and. Normally, it acts like a single-shot break action shotgun, but when upgraded, it becomes The Sweeper, with a 2 round magazine and 120 ammo in reserve. Suprisingly, the Blundergat has low recoil, despite its multiple cannon-like barrels.

When combined with the Acid Gat Kit, it becomes the Acid Gat. It has an automatic 3-round magazine. When a zombie is shot while in its upgraded form, they will be stuck with an acid infused round which explodes soon after. When Pack-A-Punched, it becomes the Vitrolic Withering which makes the acid shots attract zombies similarly to the upgraded Crossbow and Monkey Bomb. The Vitriolic Withering starts to make crawlers at around rounds 20 to 23.

There are 2 ways of obtaining the gun, one being from the Mystery Box, and the other from finding 5 hidden skulls throughout the map. These can be obtained by throwing the Hell's Retriever at the skulls, and from that point proceeding to the Warden's Office where a Blundergat will spawn on his desk. This method allows 2 players to obtain the Blundergat at the same time. This can also allow one player to have both the Blundergat/The Sweeper and the Acid Gat/Vitriolic Withering at one time.
