- "Pump-action shotgun. Reliable 2-shot kill with a short 1 hit kill range."
- — In-game description
Unlike most pump-action shotguns in the Call of Duty series, it is defined by its extremely low one hit kill range, being more suited for two shot kills.
The MOG 12 appears in all zombie maps where it's available on the wall for 1000 points and as a weapon within the Mystery Box for 950 points, or can be selected as a starting weapon once unlocked and equipped in the player's loadout. When upgraded via Pack-a-Punch Machine, it becomes the OMG Right Hook with the magazine size increased to 16 shells and its ammo reserve increased to 64.
- The MOG 12's red iron sight originally glowed like an LED, but this was changed in the full release.
