A shotgun is a lethal close-range weapon. Though they can be powerful if used by a skilled player, they are rarely used because of their weak damage at medium range and small ammo clip. At close range, a shotgun can kill two armored opponents with one shot.
Shotguns are usually chambered with 12 gauge buckshot as their ammunition. They are very suitable for close quarters combat due to their high damage. The shotgun has the poorest Kevlar penetration power due to its caliber. They are almost useless at long range, due to the buckshot spreading as distance increases; some shotguns remedy this by firing slugs, such as the Volcano and the SKULL-11. None can be fired underwater. Most can do high knockback against zombies. All shotguns cannot be fired underwater.
