Moonstone is the second Mastery camo for the Co-op Campaign in Call of Duty: Black Ops 7, and it marks the point at which the grind shifts from individual weapons to entire weapon classes.
It sits right after Molten Gold and acts as the bridge into Chroma Flux and Genesis.
Unlocking it always follows the same structure, but it demands much more preparation since the challenge only appears once every gun in that weapon’s category has already reached Molten Gold.
How Do Class Requirements Work for Moonstone?
Moonstone won’t show up the moment a single gun is done, since the game waits for the whole class to hit Molten Gold.
That means completing all Military and Special camos for every weapon in that category and then finishing the 20-Special-enemy requirement for each one.
The bigger classes like assault rifles and SMGs need Molten Gold across all six guns, mid-sized classes like shotguns, marksman rifles, snipers, and pistols require three apiece, and the smaller sets like LMGs, launchers, and melee weapons only need two.
Once the full class is cleared, the Moonstone challenge becomes available for the weapon you're targeting.
How Do You Finally Unlock Moonstone?
Once the class-wide Molten Gold requirement is done, the game reveals the Moonstone objective for that specific weapon: eliminate 100 enemies in Zone III or Zone IV of Endgame using only that gun.

These higher-tier zones are where enemies hit hardest, so the counter only moves when you secure the kill with your chosen weapon inside these danger areas.
The most reliable method is to raise your Combat Rating in Zones I and II, then move into Zones III/IV once your gear is locked in, keeping to safe engagements and steady sightlines.
Kills earned through streaks, vehicles, or anything else won’t count, since the weapon itself must land the last blow.
After all 100 high-tier enemies have been taken down with that weapon, its Moonstone camo unlocks in the Co-op mastery menu.
