The ATSG-12 is a fully automatic shotgun made largely out of stainless steel. It is a multi-functional weapon that can clear a room with efficiency.
―In-game Description

The ATSG-12 is a shotgun that appears in Watch Dogs and Watch Dogs 2.


The shotgun is clearly based on the design of the MPS AA-12/ Atchisson Assault Shotgun. The in-game model features the same integrated fixed stock and a deep grey camouflage scheme across its body. Like its real life counterpart, the ATSG-12 is fitted with two iron sights. The in-game model employs eight-round box magazines (although they actually hold twelve rounds), each loaded with 12-gauge shells.

The ATGS-12 is unique in being a shotgun with full-auto capability, due to its employment of an API blowback operation system. The system gives the ATSG-12 firing capability similar to that of an Assault Rifle.


The gun's employment of 12-gauge shells, combined with its full-auto capability allow it to deal heavy damage at a quick rate for a good sustained duration (for a shotgun). The gun is ideally suited to taking down large numbers of close-medium range targets quickly. It is also well-suited to destroying vehicles, with one magazine being able to disable or destroy most cars even without the "Anti-Vehicle Rounds" skill. The damage per round, rate of fire and sustained fire duration make the ATSG-12 arguably the most deadly non-explosive gun in-game, as it takes 2 shots at close range to kill a single Gunman and 4 to kill an Elite, at short-medium range. However, the ATSG-12 barely does any damage to Enforcers due their heavy Ballistics armor, an explosive weapon being a better choice when fighting Enforcers. Sustained fire, however, may deal severe damage to one, especially at close range.
