Harmonic Break Camo

1. Tier 1Gold
2. Tier 2Platinum
3. Tier 3Harmonic Break
4. Tier 4Divergence

Step by step

1. Level the weapon to unlock its 8 Military camos. The levels needed differ by weapon.
2. Complete the weapon’s 3 Special camo challenges. They open at set weapon levels, and DMZ asks for more kills than Multiplayer.
3. Gold: get 15 kills in a single Multiplayer match, or 100 in a single DMZ match.
4. Platinum: once every weapon in the class has Gold, complete that class’s Platinum challenge.
5. Harmonic Break: once all 33 weapons have Platinum, complete the class’s Harmonic Break challenge.

Challenge by weapon class

Example: for the Han 86, Platinum all 33 weapons first, then get 25 double kills on players in Multiplayer or 50 on enemies in DMZ. Progress from both modes counts.

Requirements from the official Call of Duty blog: Modern Warfare 4 progression and Prestige. See every endgame camo on the MW4 Mastery camos page.
