Mob of the Dead Blundergat Guide and Upgrade Methods

The Blundergat is widely recognized as the defining Wonder Weapon of Mob of the Dead in Call of Duty: Black Ops II. Combining the devastation of a quadruple-barreled shotgun with unique upgrade paths, this weapon is vital for players aiming to reach high rounds on Alcatraz Island. Understanding how to acquire and transform this firearm ensures better survival strategies during intense horde encounters.

Obtaining the Blundergat on Alcatraz Island

Players can secure the Blundergat through two distinct primary methods depending on luck and exploration effort. The standard option relies on spinning the Mystery Box throughout the prison complex until the weapon appears. Alternatively, players can unlock a guaranteed free Blundergat by collecting five hidden skull items scattered across the map using the Hell's Retriever.

Finding all five blue skulls requires precise throwing skill with the spectral retriever weapon. These skulls reside in locations such as the Warden's desk, a cell light, a dock pole, a toilet, and a rooftop corner. Once retrieved, the free weapon spawns atop the desk in the Warden's Office for any player to claim.

Converting to the Acid Gat

Transforming the base weapon into the Acid Gat greatly enhances its crowd control capabilities. Players must gather three specific crafting parts hidden in the Infirmary, Warden's Office, and Docks areas. After collecting the engine, kit, and case, assembling them at any available workbench creates the Acid Gat conversion kit.

Placing the weapon into the finished kit converts it into a explosive-projectile launcher. The Acid Gat fires three three-round bursts of sticky acid canisters that attract nearby zombies before exploding. This decoy effect acts similarly to a Monkey Bomb, granting essential breathing room during emergencies.

Pack-a-Punch Upgrades and Sweeper Form

Enhancing the Blundergat through the Pack-a-Punch machine located on Golden Gate Bridge yields dramatic stat boosts. Placing the original un-upgraded shotgun into the machine yields The Sweeper, which drastically increases magazine size and damage output. The Sweeper decimates undead trains with incredible force, making it a reliable close-quarters powerhouse.

Players can also upgrade the Acid Gat version via the Pack-a-Punch machine to create the Vitriolic Withering. This ultimate variant features higher ammo capacity, increased explosive radius, and extended distraction durations. It remains one of the most powerful weapons in Zombies history for managing late-game rounds.

Strategic Tips for High-Round Survival

Maximizing the efficiency of your upgraded Blundergat requires smart positioning and perk selection. Pairing the Vitriolic Withering with Speed Cola significantly reduces the lengthy reload animations between bursts. Managing ammo carefully is also crucial, as explosive rounds can deplete rapidly during prolonged defense sequences.

Utilizing Electric Burst and Ph D Flopper alongside the weapon protects players from self-inflicted splash damage. Training zombies through the Cafeteria or Gondola pathways provides optimal sightlines to deploy acid shots safely. Mastering these tactics allows teams and solo players alike to achieve massive round scores on Alcatraz.
