One of the several differences between Call of Duty multiplayer and Zombies mode is the presence of ammo mods. Introduced in Black Ops 4, the system is back again in Black Ops 6. They act as weapon modifiers on your ammo, giving them different effects and in a sense, upgrading them. So let’s dive into all of the ammo mods in the game and the effects you can expect when using them.

There are five different ammo mods for the Zombies game mode in Call of Duty Black Ops 6. Four of them have been in MW3 Zombies and Black Ops Cold War before, with one new addition, Shadow Rift, joining the group. In addition to their normal effects, ammo mods can be upgraded with Augments, with Major and Minor augments available for research. With that, this table lists all the ammo mods in BO6 and their effects:

Ammo modLevel to unlockEffect
Dead WireLevel 1Your bullets deal electrical damage and have a chance to stun a Normal or Special enemy, which in turn generate an electric field that damages nearby enemies.
Napalm BurstLevel 6Your bullets deal fire damage and have a chance to ignite Normal and Special enemies.

How to get ammo mods in Black Ops 6 Zombies

There are two ways to get ammo mods in BO6. The first method is to purchase them from the Arsenal Machine using Salvage as currency. The second method is to pick them up from ground loot. However, they are a rare drop, so it’s not a very sustainable method of acquisition. The best way is to save up Salvage and buy the ones you want directly.

Available Augments for all ammo mods in Black Ops 6

Once you reach Level 11, you will unlock the Augment Research option, which extends to both ammo mods and perks. This will let you pick and choose between upgrades that you focus on. Unlike previous iterations of this system, in Black Ops 6, you won’t have to grind currency to research Augments. Each ammo mod has two types of Augments, split into Major and Minor, with three options in each category.
