Bungie and Activision have shown off the first look at Destiny 2 gameplay and provided additional details around the game. One big addition to the sequel is that it is coming to PC. For PC-based gamers, you’ll need to have a Battle.net account since the game is releasing exclusively on that platform.

This means that there will be no release on Steam, Good Old Games or Windows Store, at least not anytime soon.
Destiny 2 launches for PC, PlayStation 4 and Xbox One on the 8th September.
