Infinite Grenades is a power-up featured in Call of Duty: Infinite Warfare Zombies mode. It gives all players an unlimited amount of primary grenades. It takes the appearance of a bright green Infinity symbol with a small grenade icon that tosses itself over the symbol.
If the player has only one grenade in their inventory, they will be unable to have two live grenades active at the same time, as the grenade counter will sit at zero. When the first grenade explodes, the player will be able to throw another one. As such, this power-up is most effective with the Bio Spike and C4 pickups, as they detonate quickly or can be self detonated respectively.
It is dropped from a normal zombie usually, but can be dropped by the Brute when killed.
