"Uses shotgun ammo. Most would agree that against walking piles of half rotted flesh the shotgun makes a grand weapon. Easily accessible and devastating. What's even better than a shotgun? The offspring of an illicit encounter between a regular shotgun and an assault rifle = automatic shotgun."
―NK Store Description

The AA-12 is unlocked at Rank 6 in Zombie Assault 3. It costs 25 NK coins (previously 2,400 MochiCoins; $2.99 on the iOS/Android version). Ammunition for this gun costs $75 for 25 rounds. If all the pellets connect, the AA-12 will deal 1,120 damage, the same amount of damage as the Stoeger side-by-side. It fires at 400 rpm, or 6.66 rounds per second. The magazine size is 20 shells, very large for a shotgun but rather small in overall terms. Because of its high damage, spread, pierce, and fire rate, the AA-12 is excellent for use against crowds or large numbers of tougher zombies.


  • The Shotlite Tempest from SAS: Zombie assault 4 appears to be a futuristic version of this weapon due to its similar nature and look.
