Armory Unlock Challenges can be completed by completing a specified number of Daily Challenges, which typically range from two to five. Armory Unlocks will unlock via a set order determined by the game unless you manually initiate challenges, which we highly recommend. Three Armory Unlocks can be queued at any time, and you can switch your current active challenge by simply activating a new one. Doing so will move your previously activated challenge to number two in the queue.
