Destiny 2 is about to be transformed in many ways, about half a year after Bungie split with Activision to independently take the reins of the franchise.

On September 17th, the PC version of the game will move from Battle.net to Steam. That’s just the tip of the iceberg, though, as on the same day Bungie is also launching on all platforms the free-to-play version of the game, New Light, and a new paid expansion, Shadowkeep.
