Microsoft dropped the incredible news earlier this year that it would be acquiring Zenimax Media, which also includes developer Bethesda. The studio's biggest release this year, Doom Eternal, also launched on Xbox Game Pass only several months later.
Undoubtedly one of the most ambitious games of 2020, the sequel to 2016's DOOM is one hell of a time. Play as the Doomslayer as he rips through demonic hordes of enemies.
While the 2016 game left the Xbox Game Pass service a while ago, hopefully the new acquisition means that it could come back sometime in the future. If you've already played it, now is a great time to try it out on Microsoft's game subscription service.
