Peacekeeper

"Fully automatic personal defense weapon. Rifle-class accuracy and range with SMG speed and handling."

- Description

The Peacekeeper is a submachine gun featured in the Call of Duty: Black Ops II's downloadable content pack Revolution.

Multiplayer
The Peacekeeper has the lightweight design of a submachine gun, but with better range and accuracy at the cost of close quarters firepower, essentially being a hybrid between a submachine gun and an assault rifle. It has the one of the lowest damage outputs, and the lowest rate of fire out of all submachine guns (tied with the PDW-57 and MSMC); as a result suffering in close quarters combat, even being outgunned by certain assault rifles and light machine guns; however, it outperforms all other submachine guns in terms of range, with its four to six-hit-kill range matching (and in some cases, exceeding) those of assault rifles. In exchange for this impressive range, its close range time to kill is relatively long and it has moderate-low recoil. In addition, the Peacekeeper requires an assault rifle's default 0.25 seconds to aim down the sights as opposed to the submachine gun's default 0.2 seconds.

In order to unlock Diamond Camouflage for the Peacekeeper, all other submachine guns as well as the Peacekeeper must have Gold Camouflage unlocked. However, unlocking camouflages for the Peacekeeper is not required to obtain Diamond on other submachine guns.
