The number of weapon camos available in the game without any DLC is pretty high and after including all the purchasable and pre order related camos, the list becomes huge and will undoubtedly keep on growing as more camos are released.
Weapon appearance can be altered in two ways, equip a full gun camo or perform custom painjobs to cover specific parts of the weapon for a more unique look.
Below is a list of all the camos available in the game to customize weapons and instructions on how to find them:
Campaign Camos: there are a total of 4 camos available in the game that are unlocked for multiplayer after progressing through the main campaign of Black Ops 3.
