Activision Blizzard titles have been slow to come to Xbox Game Pass since Microsoft’s 2023 acquisition of the company. While the service did get a day-one release of Call of Duty: Black Ops 6 and now hosts several other Activision titles, its current lineup barely scratches the surface of Activision Blizzard’s immense library. Disappointing as it may be for some users, there may be a good reason why Xbox Game Pass has taken so long to include more of these games.
