Aside from Doom Eternal, some other games from Bethesda that haven’t hit Xbox Game Pass yet will also be added to the service in the future.
With Microsoft acquiring ZeniMax, all the games from Bethesda will join Xbox Game Pass sooner or later, but it seems Doom Eternal will be the first title to land on Game Pass after merging to the Xbox family.
So, Doom Eternal might be the biggest surprise in October for all the Game Pass subscribers on Xbox One and PC.
As you may guess, Slayer is the name for the protagonist in Doom Eternal, and the term above likely teases its addition to Xbox Game Pass in the near future.
