Machine Gun

A Machine Gun is a fully-automatic mounted or portable firearm, usually designed to fire ammunition cartridges in quick succession from an ammunition belt or large-capacity magazine, typically at a rate of several hundred rounds per minute.

Overview
A machine gunner's job is to provide covering fire for other troops to move up. This is better for belt-fed machine guns like the RPD and M60E4 from Call of Duty: Modern Warfare. However, some machine guns have low ammo capacity, and are sometimes treated like an assault rifle like the BAR from Call of Duty: World at War, and the HK21 in Call of Duty: Black Ops.

Most machine guns have a high rate of fire, high damage, and high ammo capacity. However, the user sacrifices fast movement speed and in some cases, high accuracy. Hip-firing is at best, a panic option, as most LMGs have larger crosshairs than an assault rifle and a submachine gun due to their weight. Machine guns also have the advantage of shooting through obstacles, something the assault rifles and SMGs can't match.

Overall, the machine gun has been defined in various Call of Duty games, for example, Call of Duty 4 had primarily belt-fed machine guns, and in Call of Duty Black Ops, the only belt-fed machine gun is the M60, others, like the Stoner 63 and HK21, have a magazine size of 30 rounds, which depletes quickly and results in a low ammo capacity.

Zombies
Machine guns prove to be great and efficient weapons in the Zombies game mode, only bested by the Wonder Weapons. Most machine guns feature high ammo capacities, high rate of fire, high damage and large magazines. However, this is offset by their long reload times and sluggish handling and performance, making Speed Cola and Stamin-Up essential. Their characteristics suit defensive and low mobility playstyles, as machine guns can gun down large groups of zombies quickly and perform at their peak when stationary, however, they lack speedy handling thus making them a poor choice for players who want to move swiftly around areas. Because of their high value, machine guns are fairly rare in the Mystery Box.
