The Blundergat is a Wonder Weapon featured in the Zombies map Mob of the Dead in Call of Duty: Black Ops II, as well as its reimagining, Blood of the Dead, in Call of Duty: Black Ops 4. It is based on civil war-era weaponry, consisting of ideas from the both the Blunderbuss and Gatling gun. Without upgrades, it acts like a single-shot break-action shotgun, with a one-round magazine and 60 in reserve. Unlike a typical shotgun, the pellets spread out in a completely horizontal line. It is also the first and only Wonder Weapon to shoot regular bullets.


Black Ops II

When Pack-a-Punched via the Pack-a-Punch Machine, it becomes The Sweeper, with a two-round magazine and 120 in reserve. The Sweeper is very powerful, being able to kill zombies with one hit until Round 40 if one has Double Tap and aims for the head.

Double Tap Root Beer is a very effective perk for the Blundergat as well as The Sweeper, as it doubles the amount of pellets shot and thus potential damage as well. Speed Cola is recommended as well due to the frequent and somewhat lengthy reloads. Electric Cherry can be very useful when using the Blundergat, as the player is left very vulnerable during the constant reloads, and the effect of the perk is usually maximized (as the shock effect is higher the emptier the magazine is) due to the low ammo before reloads. Juggernog is also useful as the Blundergat is most effective up close where the player is bound to take more attacks from zombies.

In addition to Mystery Box, the Blundergat can be obtained after collecting five hidden blue skulls around the map by throwing the Hell's Retriever at them. These skulls can only be seen in Afterlife, although their locations always stay the same each game.

  • Two can be found at the docks: the first being on a lamppost opposite and to the left of Juggernog on a hill, and the other being on a pillar (third from the left) near the possible Mystery Box spawn.
  • One can be found on the roof, near the far-left corner (when coming to the roof), sitting on an unreachable corner of the roof.
  • One can be found in a jail cell with a toilet and a skull next to the library near the starting room.
  • One can be found near the Warden's Office, in an electric pylon outside the barrier next to Speed Cola (it is recommended to not repair the barrier as the planks can make throwing the Hell's Retriever at the correct spot difficult).

Blundergat vs The Sweeper

Damage 1500 5000
Fire mode Single-Shot Semi-Automatic
Magazine size 1 2
Max ammo 60+1 120+2
Mobility High High
Extras Becomes semi-automatic with an increased magazine capacity, more ammo.


When upgraded with the Acid Gat Kit, it becomes the Acidgat. It has a three-round magazine and fires in bursts of three rounds. The projectiles stick to walls and other objects (including zombies), and will explode soon after. When shot, the projectiles will typically spread in a very wide angle instead of going where the player aims. These rounds are also capable of hurting the player, although the explosion is somewhat minor and should not considerably damage the player unless already severely hurt. When a zombie is hit by a projectile, they will stand in place until it explodes.

When the Acidgat is Pack-a-Punched, it becomes the Vitriolic Withering, with increased damage, twice as many projectiles per shot, and the projectiles attract zombies similarly to the upgraded Crossbow and Monkey Bomb. The Vitriolic Withering starts to make crawlers at around rounds 20 to 23.

Due to the self-inflicted damage, Juggernog is useful to minimize the chance of downing oneself or do enough damage for a single attack to down the player. Double Tap Root Beer is questionable, as it only helps in firing the three projectiles within the burst faster without increasing damage. As with the regular Blundergat, Speed Cola helps with the constant and long reloads, and Electric Cherry also helps to protect the player during these reloads.

In Blood of the Dead, a new upgraded version of the Blundergat titled the Magmagat makes its debut. This version shoots a blob of molten lava that can stick to surfaces and attract zombies, killing them after making contact with the blob.

In order to obtain the Magmagat, the player must acquire a Blundergat from either the Mystery Box or the free Blundergat easter egg. The player must travel to the Warden's House and place the Blundergat in the fireplace. This will cause the player to be locked within the room until the player completes the next step, which involves getting kills. After getting a certain amount of kills, the three skulls above the fireplace will all be alight in a blue fire. The player can now deposit the souls collected during the previous step, creating a "Tempered Blundergat" that is on fire. The player must now head to the New Industries whilst the Blundergat has its fire, which can be replenished by walking up to barrels of blue fire.

Upon reaching the New Industries, the player can placed the Tempered Blundergat into a compressing machine, causing two ghosts to use the machine to create the Magmagat. Once the player does this for the first time, any other player in the game can upgrade their Blundergat into a Magmagat by simply placing it in the machine in the New Industries.

When the Magmagat is upgraded in the Pack-a-Punch Machine, it becomes the Magmus Operandi. This gives the weapon an additional shot in the barrel, as well as increase the damage caused by the blob, which can instantly kill Brutus should he walk over it.
