In addition to revealing details on the next major expansion for Destiny 2, an add-on titled Forsaken, today Bungie talked more about future content coming to the game. Bungie already has plans for Destiny 2 content updates coming through summer 2019, and is now selling an “Annual Pass” that offers players exclusive access to that content.

Bungie and publisher Activision are already selling Destiny 2’s Annual Pass on the game’s website as part of a bundle. That bundle, which includes Forsaken and the Annual Pass, costs $69.99. Destiny 2: Forsaken costs $39.99 on its own, so the Annual Pass is a $30 premium. Think of it like a season pass for an expansion.
