Modern Warfare 3 camos are divided into two types: Base and Mastery. Before you can unlock the fancy mastery camos, you’ll need to acquire base camos first. Base camos are a bit different this year, but in a surprisingly good way. There are over 180 base camos, and they are all universal this year. Meaning, once you unlock a base camo for one weapon, you’ll be able to apply it to all other weapons in your arsenal. These are no longer weapon-specific base camos.
There are a maximum of four base camo challenges for each Gunsmithable weapon in the game, and you’ll get access to these camo challenges as you level up the weapon. These vary from weapon to weapon, but these are simple challenges like getting a certain amount of kills, double kills, and such. Launchers and melee weapons (weapons without attachments) that aren’t customizable in the Gunsmith only have one base challenge each.
To get started and view the camo challenges, you’ll want to choose a weapon, select the Gunsmith, and tab over to the Customize section. This is where you can view camos, stickers, and weapon charms for customizing your weapons.
It’s worth noting here that the four base challenges will unlock as you level up the weapon, and these unlock levels vary from weapon to weapon.
For example, the .50 GS pistol’s base challenges unlock at levels 2, 10, 18, and 26, while the M4 assault rifle’s base challenges unlock at 2, 8, 13, and 19. Make sure to check out our guide on how to level weapons faster in Modern Warfare 3, and you’ll be completing camo challenges in no time.
Once you have completed all of the base camo challenges for a specific weapon, you will unlock your first mastery challenge, which is for the Gold camo.
