A specialist Insurgency shotgun. The weapon is 12-gauge, double-barrelled, and high-capacity. Its users work in a quick, calculated, and efficient manner — they incapacitate, execute, and move on to the next target.

It is often found that Foundation psychologists need to treat even the most experienced guards. It is claimed that sometimes, in some distant hallway, they still hear the weapon being cycled.

“It’s not unusual to see shotguns used during indoor combat scenarios, especially where breaching doors may be involved. What is unusual, is the Insurgency’s shotgun of choice. By all accounts, the weapon is unnecessarily heavy, overly-complex, and should be of questionable practicality.
I’ve seen security footage of some of their previous raids. The guns seem to be used to great effect. They’re never issued in large numbers. It seems that the troops using them are trained with a specialized role in mind, complete with a two-shot execution system.
The Insurgency seems unusually well-practiced when it comes to site infiltration. Sites are breached with frightening efficiency. Insurgency squads have several roles, one of which appears to be a “tactical breach specialist”. When it comes to those armed with a shotgun, their job is to take care of any stragglers. After the initial defenses are overwhelmed, “insurgency breachers” will detach from their squads to execute any survivors.
I don’t think I’ll ever be able to unsee that footage. To see someone’s head blown into meaty chunks with a single shot is a gut-wrenching spectacle.”
