Ammunition types are not only defined by projectiles in SURGE!, but also anything that can be depleted through its use. A battery, for example, is required to power a flashlight. When the battery dies, the flashlight loses functionality until the battery is replaced with another, much like projectiles are expended once fired or released from its weapon.
