As part of its continued effort to expand the amount of content available to non-DLC owners, Bungie has released a new Destiny 2 update on PS4, Xbox One, and PC. Rather than address any bugs or exploits, this patch deals exclusively with undoing the studio's previous decision to lock those who haven't purchased Curse of Osiris out of content they had access to previously.
