Ammo
Ammo is the amount of ammunition a weapon has available. On weapon list pages, ammo is usually shown as the amount loaded in the weapon followed by reserve ammunition.
Ammo Display
A value such as 30 / 90 means the weapon has 30 rounds loaded and 90 rounds in reserve. Some weapons can also show +1, meaning they can carry one extra round in the chamber in addition to a full magazine.
Shotguns, revolvers, grenade launchers, and other weapons may use smaller loaded counts or special reload behavior. Dual weapons can also show combined ammo values for both weapons.
Extra Ammunition
Some loadouts or equipment choices can affect how much ammunition a player carries. Extra ammunition is useful for staying in a fight longer, but it can also increase Weight depending on the item or loadout.
