In a surprise announcement for Bungie Day 2018 — the developer’s community focused holiday, which takes place on July 7 each year — the studio revealed that the Moments of Triumph for Destiny 2’s first year are now live. Players can go to Bungie’s website to begin tracking their progress toward receiving the in-game rewards that launch later this month.

The Moments of Triumph are essentially miniature in-game achievements. For example, some of this year’s Moments of Triumph challenges include completing each of the game’s campaigns, the Leviathan raid, and collecting Exotic gear. Each of these accomplishments will net players points that they can eventually use to unlock exclusive cosmetics.
