Updated: the Doom Eternal Xbox Game Pass launch has now been confirmed and it arrives in early October 2020 on Xbox One.
A news post from Xbox reveals what was strongly suggested by the earlier teaser: Doom Eternal is coming to Xbox Game Pass for the Xbox One. Unfortunately, PC players will not gain the benefit of a simultaneous launch — they'll have to wait until a little later in the year.
A Doom Eternal Xbox Game Pass launch seems all but certain due to a recent cryptic message posted on the service's official account.
Doom Eternal is the sequel to the 2016 Doom revival and it's proved to be a boatload of fun. The game's been out for a while now, but it's only been available as a standalone purchase on PC and consoles. Now, it seems likely that a Doom Eternal Xbox Game Pass launch is coming soon.
The hints for this launch are cryptically buried within a tweet posted to the official Xbox Game Pass account:
Melissa said not to drop hints so we're not dropping hints. there are absolutely no hints in this screenshot. don't bother looking for them. there are none pic.twitter.com/0PQ41B260S

Despite saying that there are "absolutely no hints" in the above tweet, we naturally went looking for them. Several replies to that tweet purport to show a secret message placed right below Melissa's name, but I couldn't see it for the life of me.
I tilted both of my monitors and my phone to no avail, but I was eventually able to uncover the secret message hidden in the screenshot with the help of my colleagues. (Why I couldn't see it is a complete mystery to me.) Here it is, plain as day: "The Slayer is Coming."

When is the Doom Eternal Xbox Game Pass launch?
The Doom Eternal Xbox Game Pass launch will be on October 1, 2020 for Xbox One according to the Xbox news post. It will be coming to PC later sometime in 2020. There was no firm date for the launchwhen the teaser was revealed, although it did state that a game is "coming to the service very soon."
2016's Doom was already on Xbox Game Pass, but Microsoft's acquisition of Bethesda's parent company Zenimax makes adding it back to the service a trivial matter, and fulfill Microsoft's promise to bring Zenimax's games to Game Pass. It'd seem very odd to hype up the return of a game that was already on the service, so the odds look good that we'll be seeing a Doom Eternal Xbox Game Pass launch in the near future. For those wondering about the classic Doom games, those are very possible as well, but in the classic titles he was just Doom Guy, with the reimagining of sorts starting with Doom 2016, he has been going by Doom Slayer.
