“Ad victoriam! The Steel Reign Update is coming in July, and you can prepare for the new questline by getting fully decked out in Brotherhood gear with “The Coming Storm,” a limited-time in-game event that kicks off June 15.”— Inside the Vault
The promotion revolved around a free Brotherhood of Steel backpack skin in the Atomic Shop. Players were tasked with completing special Daily Challenges while wearing a backpack equipped with the skin. The tasks ranged from completing an Event in a particular region to laying claim to a Workshop. Each Daily Challenge progressed toward a Weekly Challenge, in addition to awarding a consumable item. Completing 3 Daily Challenges in a given week would unlock a Brotherhood of Steel themed reward. Completing 2 of the 3 Weekly Challenges would unlock a secret bonus award.
