Well-known leaker eXtas1s is reporting that Xbox Game Studios Publishing will be working with Ancestors: The Humankind Odyssey dev Panache on a new project. 2019's Ancestors was the much-talked about adventure game from the creator of Assassin's Creed - and at this point it's still the only game to have been released by Panache.
The report doesn't contain much more detail than that, aside from the fact that the game is using Unreal Engine 5, and it might not release until 2026 or 2027. EXtas1s also speculates that it could be a game called '1666: Amsterdam' that's been worked on by the ex-AC developer for some time - but that's just conjecture at this stage.
To that point, it's probably worth taking this whole rumour with a pinch of salt for now. While eXtas1s does have a decent track record, it sounds like this project is a ways off from launching, and we haven't heard anything official from Microsoft on the matter just yet.
2K subsidiary Private Division published the team's first game, Ancestors: The Humankind Odyssey, but it hasn't announced any sort of deal for a future Panache project. We'll have to wait and see what happens with this one, but it sounds like Xbox could be busy striking even more publishing deals behind the scenes!
In the meantime, Ancestors is discounted on Xbox right now, and it looks like it's a proving to be a pretty popular Xbox Store pickup at the moment.
