Helio
Last verified 2026-11-03 · Sources: Call of Duty progression blog and patch notes, checked 2026-10-26
The third DMZ mastery camo.
Short answer Helio: 25,000 kills with Legendary weapons on a max-level Operator, after Ripple Tide; DMZ account-wide.
Requirement
| Mode | Camo | Requirement |
|---|---|---|
| DMZ | Helio | 25,000 kills with Legendary weapons on a max-level Operator |
When it unlocks
Helio is account-wide and opens after Ripple Tide. It is the last published DMZ mastery camo in the chain.
How to progress
- Both conditions matter: the weapon must be Legendary and the Operator must be max level.
- Track kills, not deployments; 25,000 is a long count.
- Keep the Legendary weapon and max-level Operator setup consistent so every kill qualifies.
Common mistake
Using a Legendary weapon on a non-max Operator, or a max Operator with a lower-rarity weapon. Either mismatch breaks the qualification.

What else do players ask about MW4 camos?
What is the MW4 camo order?
Per the official Call of Duty blog: 8 Military camos (weapon level), 3 Special camos, Gold, Platinum, Harmonic Break, then the Divergence mastery camo.
How do I unlock Gold camo in MW4?
Get 15 kills in a single Multiplayer match, or 100 kills in a single DMZ match, with that weapon.
How do I unlock Platinum?
Earn Gold on every weapon in the class, then finish the class challenge. Assault Rifles: 50 headshots in Multiplayer or 100 in DMZ.
How do Harmonic Break and Divergence unlock?
Harmonic Break needs Platinum on all 33 weapons plus a class challenge (Assault Rifles: 25 double kills in MP or 50 in DMZ). Divergence needs Harmonic Break on all 33 weapons.
Why are some challenges marked unverified?
Activision has published full Special camo challenges only for the Han 86 and Sang 9mm. For the other 31 weapons we show community-reported challenges from a pre-launch sheet, clearly flagged, because the launch patch says some in-game requirements were corrected.
