Earlier this year, Bungie said it planned to alter how Destiny 2 players earned rewards, particularly the cosmetic goods available to unlock or purchase from the in-game Eververse store. The goal, Bungie said at the time, was to better reward Destiny 2 players for completing activities and “give players more direct purchase options and make adjustments to Bright Engrams to allow players to get the items they want more often.”

This week, Bungie detailed how Eververse rewards are changing with season 3 of Destiny 2, which launches next week.
