When Destiny 2 released, it brought with it a bunch of content for PS4 only, and that offering continued to grow over the release of its two expansions Curse of Osiris and Warmind. Now, with the arrival of its third expansion Forsaken, Bungie has released a 2.0.0.1 update that unlocks all previous PS4-exclusives for players on Xbox One and PC.

The original game came with an exclusive Exotic sniper rifle, called Borealis. There were also exclusive armor sets for Warlocks, Titans, and Hunters, and an exclusive ship, the City Apex, all of which Xbox One and PC players can now access. A previously PS4-exclusive Strike, called Lake of Shadows, can now be found for all players in the European Dead Zone.
