Ammunition

Ammunition is any item which the player character must possess in order to attack with a particular weapon, and which is consumed in the process.

Self-contained, consumable weapons such as grenades and throwing knives are not considered ammunition.

This mechanic is most commonly used for ranged weapons (with bullets, arrows, and missiles being common examples of ammunition), but some melee weapons require ammo as well (for example, an electrified knife which consumes a charge with each attack).

Common elements

 * Games which allow the player to equip multiple ammo-requiring weapons may treat ammo as a generic, interchangeable resource (i.e., all weapons use the same pool of ammo), or they may have different types of ammo for different weapons (e.g., 9 mm ammo for handguns and 7.62 mm ammo for rifles).
 * Ammunition may or may not have weight.
 * Enemies and companions may obey similar ammo restrictions as the player, may have unlimited ammo, or may obey other rules.
 * Ammo is commonly acquired by purchasing it, finding it as loot, and/or crafting.
