Infinite Ammo is a power-up featured in Call of Duty: Infinite Warfare Zombies mode. It gives all players an unlimited amount of ammunition in their magazine, allowing for a hefty amount of damage to be dealt without the requirement to reload or watch for ammo reserves. It does not, however, affect grenades, as that is the effect of the Infinite Grenades power-up. It appears as an Infinity symbol, with a bullet that fires from the symbol. When under effect, the ammo counter will turn into an Infinity symbol, to indicate the effect.
An Infinite Ammo power-up can be forcefully spawned with the Raining Bullets Fortune Card.
