The camo challenges grind has never been bigger in a Call of Duty game, thanks to the huge, growing list of all camos in Modern Warfare 3.

There are separate challenges to unlock camos for CoD: MW3 guns and guns brought from MW2 as part of the Carry Forward system. There are 36 new weapons in MW3 at launch, and most of them have eight camos to unlock, including four base camos and four Mastery camos, with some exceptions. And then there are the separate Zombies camos, too.
