There were recent rumors that the upcoming Call of Duty game would be added to Game Pass on launch day. However, due to the scale of the move, Microsoft also plans to make some "changes" to the service, according to an insider.

According to Eurogamer, the insider claimed that these unspecified "changes" will come after Microsoft launches the next Call of Duty (rumored to be a new Black Ops title) on the first day of Game Pass. They said this in a thread on Resetera on May 17, after being asked if Microsoft would be introducing new costs or tiers for players who want to play the new CoD. While they didn't provide any further information on what exactly these changes would entail, it's highly likely that Microsoft will introduce a tiered payment system similar to other subscription services.

Microsoft and Activision have yet to officially announce the next Call of Duty game or whether it will appear on Game Pass. Since the two companies merged in a $69 billion deal, Microsoft has increased its direct involvement in Activision's internal workings. It's closed several of its subsidiaries, laid off thousands of employees and attempted to restructure the way the publisher operates. Now it appears that Call of Duty is the next to be shaken up within the conglomerate's structure, though we'll have to wait a little longer to see exactly what Microsoft has in store for us.

With the next CoD being developed by Treyarch, best known for their work with the Black Ops sub-franchise, many are speculating that we will see a return to the Cold War era of global politics. Treyarch’s latest installment, promptly named Call of Duty Black Ops: Cold War, was received with less than stellar reviews.
