It's been a big week for Destiny 2, as the game received a major update and its first DLC expansion, Curse of Osiris. While that's brought new stuff to do for owners of the DLC, those who have not purchased it suddenly find themselves with access to even less than they had a week ago. Players are understandably angry about this, as well as the fact that--as a result--certain Achievements and Trophies in the base game are suddenly unattainable without purchasing the DLC. Bungie has acknowledged that problem and said a fix is on the way.

The latest blog post did bring word about a fix for the bugged Prometheus Lens weapon; update 1.1.1 will address the Exotic's power in PvP next week. Additionally, we've learned the next Faction Rally's start is just days away. In the meantime, check out our Destiny 2: Curse of Osiris review in progress.
