How do you get camo on your secondary guns in modern warfare 2?

To unlock the camos for your secondary guns in Modern Warfare 2, you typically need to complete Mastery Challenges by accumulating specific amounts of kills or achievements with your secondary weapon of choice.

While requirements vary depending on the specific weapon and camo, below are some common Mastery Categories for secondary weapons in MW2:

1. Kills: Reach a certain number of kills within the game.

2. Precision Kills: Get a required number of kills while aiming down sights (ADS).

3. Headshots: Eliminate enemies with headshots.

4. Double Kills: Take down multiple opponents within a rapid time frame (usually within a few seconds).

5. Challenges: Complete specific objectives or tasks (e.g., get a certain number of "Point Blank" or "Longshot" kills).

6. Killstreaks: Earn consecutive kills without dying to achieve designated Killstreaks (e.g., 5 Killstreak, 10 Killstreak).

7. Damage Done: Accumulate a certain amount of damage dealt to opponents.

Remember that every camo may have different requirements, so the Mastery Challenges mentioned above are general categories and may vary slightly for different weapons. To see the exact requirements for a specific camo, hover over the camo or select it in the gun customization screen.

Complete these Mastery Challenges to progressively unlock the camos available for your secondary guns.
