Modern Warfare 3 – All Weapon Mastery Camo Challenges

Call of Duty: Modern Warfare 3 expands the arsenal available to players with a variety of new weapons to use on the battlefield. Integrated with Modern Warfare 2 through the Call of Duty HQ, players now have over 100 weapons at their disposal when it comes to creating custom classes and loadouts. If players missed playing Modern Warfare 2, or simply have not finished all the camos yet, players will have the opportunity to complete the objectives in Modern Warfare 3 lobbies and unlock mastery camos for every weapon across the two games.
