Destiny 2 crossplay will be arriving next year alongside transmogs and more, developer Bungie has confirmed.

Cross saving was already a thing in Bungie’s popular action MMO, and while crossplay has been mentioned on several occasions, the developer has now confirmed that it will become available in 2021. Back in June of this year, Bungie said that the feature is on its roadmap.
