This Call of Duty: Black Ops III guide is about how players can get or unlock Gold and Diamond camouflage for their weapons. Before moving on to providing you a step by step guide I would like to put up a notice that getting Gold and Diamond camouflages in Black Ops III requires a lot of patience.
To get Gold and Diamond and Camouflage for guns in Black Ops III, players will first need to get "Policia" camouflage at 100 headshots. Once this Policia camouflage gets unlocked, players will then need to unlock each and every gun camo that comes after that to unlock the Gold Camouflage. In total, there is 15 other camouflage apart from Gold and Diamond, so with simple math calculation players will need to have at least 15K headshots to get these Gold in Call of Duty: Black Ops III.
Talking about unlocking Diamond camouflage, Black Ops III players will need to get every single camo for every weapon type. In simple term, players will need atleast 100 headshots for every single gun available.
