Shotguns fall into two families, differentiated primarily by their magazines: combat shotguns and assault shotguns. Operationally, the two families strongly resemble one another, but combat shotguns have a lower rate of fire and a slightly higher degree of magnification when zoomed, while assault shotguns have a higher rate of fire, with fewer projectiles per shot. Other than magazines, the two families share most parts, though certain accessories or other parts are specific to one or the other. Different parts will influence different attributes of the weapon.
