Activision Following Microsoft’s $68.7 billion acquisition of Blizzard, the largest Blizzard IPs, including Call of Duty and Diablo, are anticipated to be included to Xbox Game Pass.
By making such IPs more accessible, these inclusions would help Microsoft achieve its objective of expanding the Xbox ecosystem’s user base. But it’s possible that Call of Duty won’t be able to sign up for the program any time soon.

Phil Spencer says that it might take some time to include the well-known first-person shooter franchise in the subscription.
Why it matters: Call of Duty is a sizable annual video game franchise, and each new edition is reputed to set new records for Activision’s sales and earnings.
Phil Spencer recently spoke with IGN about a variety of topics related to Xbox and the company’s future in the market.
This sparked a conversation regarding Activision Blizzard and how Call of Duty affected Xbox Game Pass as well. Phil Spencer made it clear that the Call of Duty titles would not be added to the subscription right away while discussing their availability.
To ensure a seamless transition for the first-person shooter franchise, more effort would be required. He went on to say: According to Phil Spencer, “mechanical work” must be finished after the merger is finalised, which will cause an unknown delay before Xbox and PC gamers can access Call of Duty in their Xbox Game Pass libraries.

Even so, the opportunity to purchase a subscription that includes almost all Call of Duty games is alluring enough to make the wait worthwhile. The Xbox backward compatibility, which guarantees that older games can be played on new systems, is largely responsible for making this feasible.
Microsoft would not be able to provide the most recent Call of Duty titles on Xbox Game Pass until 2025, according to a document, but there are still a number of games that could attract new Xbox Game Pass users.
Activision Blizzard’s merger with Microsoft has not been without its challenges, but the company is now closer than ever to owning the gaming behemoth.
Activision recently sold Ubisoft the streaming rights to its titles, but the gaming giant has since altered the agreement in response to CMA concerns, hoping to get approval before the deadline in October.
