"Full-auto submachine gun. Extremely fast fire rate with a brief spin up time."
— Description

The MicroMG 9mm is a submachine gun that was added to Call of Duty: Black Ops 4 during Operation Dark Divide on November 5th, 2019[1] first on PlayStation 4 and a week later, November 12th on Xbox One and PC.


The MicroMG 9mm acts similarly to the Death Machine in terms of functionality, where it has to spool up for a moment before it unloads an onslaught of bullets at an incredibly high rate of fire with as high levels of recoil. Because of the sheer fire rate alone, the MicroMG 9mm can be incredibly powerful at close-range combat. However, because of this high fire rate, the MicroMG 9mm has horrendously poor accuracy at mid to longer ranges, making it difficult to use in larger maps and open areas where other class of weapons are well-more suited.


The MicroMG 9mm appears in all Zombies maps where it's available via the Mystery Box for 950 points. When upgraded by the Pack-a-Punch Machine it becomes Infernal Mercy, gaining an increased base magazine size of 72, increased reserve ammo of 504 and increased damage.






  • The weapon has the logo of fictional company Royal & Kross on the side, much like the RK5 and RK 7.
