Mod Augments is a new system in Call of Duty Black Ops 6 Zombies that lets customize their mods a bit more. Ammo Mod has a dedicated research path featuring six total Augments: three minor and three major. Minor Augments give a limited but notable advantage, usually during use. Major Augmentations typically boost an item’s behavior during use. Players can choose two Augments per item, one minor, and one major, so picking the right ones is essential.
