MK.78 LMG
How do you unlock the MK.78?
The MK.78 is a full-auto light machine gun in Call of Duty: Black Ops 7, available in the base launch roster. Sources describe it as offering great damage and a high ammo count while being limited by slower mobility and handling. It is unlocked from the start, so it serves as the game's introductory LMG for sustained-fire support play.
