Xbox Game Pass subscribers will finally see the fruits of Microsoft's acquisition of Activision Blizzard later this month when Diablo 4 hits the service. Despite having a strong initial release, Diablo 4 has been struggling to maintain an audience after a series of underwhelming seasons, so its addition to Xbox Game Pass could breathe new life into a title that definitely needs it. However, it may be difficult for the game to retain a Game Pass audience, which could spell trouble for Diablo 4 on the road ahead, meaning it needs to impress newcomers when it arrives on Game Pass on March 28.
