Every weapon has four Special camos, then four Mastery camos. Multiplayer and Zombies each have their own separate grind — and you no longer need to level a gun first, so you can start the moment you unlock it.

⚡ Fastest route: in Zombies, high rounds stack kills and Ammo-Mod challenges quickly — a Pack-a-Punched weapon with an Ammo Mod knocks out several challenges at once. In Multiplayer, play objective modes like Hardpoint and Domination for target-rich lanes, and save double/triple-kill challenges for spawn-heavy maps.
Zombies Shortcut: Elemental Pop
The Elemental Pop Perk-a-Cola gives every bullet a small chance to trigger a random Ammo Mod effect even on a weapon with none equipped — useful for clearing a Mystic Gold challenge that needs a kill while affected by an Ammo Mod, on a gun you haven't Pack-a-Punched yet. Pair it with a high fire-rate weapon so the proc has more chances to land per magazine.
Cross-checked
Cross-checked on 5 September 2026 against Game8's Elemental Pop page and the wider field of Zombies wikis and guides (Call of Duty Wiki, Nazi Zombies Wiki, ScreenRant, Sportskeeda) — which agree on the wording, not the number: every one of them calls it only "a small chance" to apply a random Ammo Mod effect, and not one publishes a percentage or flags a patch that changed it. No source we found gives a proc rate for Elemental Pop, so this page does not claim one, and the trick above still reads as current as of this check. What is still unverified is the only thing reading cannot settle — nobody here has played it.
