CoD BO7 has made some much wanted changes to the camo grind this year, by simplifying things slightly but still keeping the bones of the CoD BO6 system that players enjoyed.

Some challenges are easier, but there are still around a dozen camos to earn for each weapon in each mode, alongside special camos for reaching Prestige Master 250 with every weapon in the game.
