Based on these instructions, installing Diablo 4 via Game Pass is not as seamless a process as PC subscribers had hoped for when Microsoft announced Blizzard games would hit the subscription service. Microsoft will no-doubt be hoping for less friction when other Blizzard games inevitably hit Game Pass in the future, but for now, players are essentially playing through Battle.net under the guise of Game Pass. PC Game Pass subscribers have also expressed the lack of achievements with Diablo 4. Battle.net has an achievements system of its own, but some had hoped that playing the action role-playing game through PC Game Pass would incorporate the achievements the Xbox version already has.
