Activision's prized asset was the "Call of Duty" franchise, one of the world's best-selling games, and Friday's release will be the first in the series to be available from day one on Microsoft's Xbox Game Pass subscription service
Microsoft's ambition to become the "Netflix of video games" faces a huge test this week with the release of "Call of Duty: Black Ops 6" on Friday.
The US software giant bought the game's publisher Activision-Blizzard a year ago for $69 billion in the sector's biggest takeover.
Activision's prized asset was the "Call of Duty" franchise, one of the world's best-selling games, and Friday's release will be the first in the series to be available from day one on Microsoft's Xbox Game Pass subscription service.
The game will also be available to PlayStation users—as well as on PC.
Mat Piscatella from analyst firm Circana told AFP it was "the biggest push" anyone had made to bolster a subscription platform.
