How to Get Mastery Camos in Modern Warfare 4: Divergence, Mercurial Drift and Orion Reforged

Every Call of Duty has a camo grind, and Call of Duty: Modern Warfare 4 goes deeper than most. Before you can touch the mastery camos, you need to take a whole arsenal through Gold, Platinum and Harmonic Break and then earn Divergence. Only then do Mercurial Drift, Polyatomic Reforged and Orion Reforged open up. This guide walks through the multiplayer ladder in order.

This guide is up to date for Call of Duty: Modern Warfare 4 Season 1 (live since November 6, 2026; the game launched October 23, 2026).

Quick answer

Mastery progress is tracked by mode. The three multiplayer mastery camos only count multiplayer play, while DMZ and Warzone each have their own separate mastery track.

Requirements

• Modern Warfare 4 multiplayer. Military and Special camo progress is shared between Multiplayer and DMZ, so early camos can be earned in either mode. Mastery challenges can't.
• 33 weapons at Harmonic Break. The launch arsenal had exactly 33 weapons. Season 1 adds the Cronen Osprey assault rifle and the CSG-35 SMG through the Battle Pass, and both have camo challenges of their own.
• Patience. Mastery takes 1,050 qualifying performances in total, on top of the base grind.

Step-by-step: from first camo to Orion Reforged

1. Level each weapon for its Military camos. Every weapon has eight, unlocked purely by Weapon Level. The level thresholds differ from gun to gun, so check the camo menu.
2. Finish the three Special camos. Each weapon has three combat challenges of its own; check the camo menu for the exact wording on each gun.
3. Earn Gold. With all eleven of those done, get 15 kills in a single Multiplayer match with that weapon (100 in one DMZ match also works).
4. Earn Platinum. Once every weapon in a class is Gold, each gun in that class gets its Platinum challenge.
5. Earn Harmonic Break. After Platinum, each class has a second, harder challenge.
6. Unlock Divergence. Complete 33 Harmonic Break challenges and Divergence unlocks automatically, opening the first mastery challenge.
7. Grind Mercurial Drift. Get 10 kills in a match 250 times. Progress counts with any weapon, so you don't need 250 high-kill games on every gun.
8. Move on to Polyatomic Reforged. With Mercurial Drift done, get 3 kills without taking damage 300 times.
9. Finish with Orion Reforged. The last tier asks for 5 kills without dying, 500 times.

Note: trackers disagree on how many hipfire kills the shotgun Platinum needs, so check the exact number in the in-game challenge description.

Tips for a faster grind

• Do the hard classes early. Prone kills on marksman rifles and snipers, and launcher multi-kill games, are the usual roadblocks. Knock them out while you're still fresh rather than leaving them for last.
• Work toward Gold on several guns in a class at once. Platinum only opens when the whole class is Gold, so one unfinished weapon holds up the rest.
• Play objective modes with fast respawns for kill-count challenges like Gold and Mercurial Drift. Small maps and 6v6 playlists give you more fights per match.
• Use Double Weapon XP tokens for the Military camo levels, the slowest part of the early grind.
• Lean on your most comfortable gun for mastery. Since mastery progress counts with any weapon, pick the gun you play best for the 250, 300 and 500 counts.

Common mistakes

• Grinding mastery in the wrong mode. Kills in DMZ or Warzone don't count toward Mercurial Drift. DMZ's track is Chiral, Ripple Tide and Helio, and Warzone's is Parallax, Damascus Reforged and Empyros.
• Expecting mastery camos on older guns in Warzone. Activision says mastery camos only work on Modern Warfare 4 weapons, not on legacy weapons carried over from earlier games.
• Ignoring the "without taking damage" wording. For Polyatomic Reforged, a single hit ends the streak, not just a death. Play from cover and pick fights you can win quickly.
• Skipping the Special camos. Gold won't unlock until all three are finished, even if the weapon is max level.
