Modern Warfare 3 Armory Challenges
Armory Challenges are new roadblocks in Modern Warfare 3 that you’ll have to complete in order to unlock certain weapons. You’ve probably missed them on your home screen, but don’t worry, they’re not actually that difficult to complete.
Armory Challenges can often be something as simple as “complete three daily challenges”. These Armory Challenges can be activated from the loadout menu of the gun you’re trying to unlock, once you’ve reached the pre-requisite level.
You can find what you have to do to complete the Armory Challenge under the name of the weapon in the Gunsmith.
