Diablo 4 is coming to Game Pass on March 28, 2024, but players on PC will also need to install Battle.net in order to access the latest hack-and-slash title from Blizzard Entertainment. It's been almost six months since Microsoft's acquisition of Activision Blizzard was finalized, and one of the benefits that players have been looking forward to the most has been the possibility of playing Blizzard franchises through the Game Pass. The first title to earn this privilege happened to be Diablo 4, which saw its initial release in June 2023, and is now in the middle of its third season.
