Three years after parting ways with Steam, Ubisoft signed a new deal with Valve last year to slowly bring back its games to the world's most popular digital games distribution platform. But, while most if not all of Ubisoft's most popular titles are already on Steam, one of its biggest yet likely won't be.

As per the official Assassin's Creed Mirage website, the upcoming entry in the company's best-selling franchise will be on all popular platforms but it won't be on Steam.
Here's a list of all the confirmed platforms for Assassin's Creed Mirage on October 12:
- Xbox Series S
- Xbox Series X
- Xbox One
- PlayStation 4
- PlayStation 5
- EPIC
- PC
- Amazon Luna
Unless PC is another word for Steam, it's highly unlikely that Assassin's Creed Mirage won't be available on the platform. At least, not at launch.
If this is true, expect to see Assassin's Creed Mirage spend some time exclusive to the Epic Games Store on the PC (on top of Ubisoft Connect).
Admittedly, it's weird that Ubisoft is making Assassin's Creed Mirage exclusive to one particular platform when it just went all-in on the franchise with several more games in development other than Mirage. Ubisoft is heavily reliant on the success of every Assassin's Creed outing, so making Mirage available on as many platforms as possible is the best source of action. After all, Steam is the most popular digital games storefront, and skipping a release there would certainly have a negative impact on the bottom line.
Of course, Epic could have paid Ubisoft a massive sum to make it exclusive to the Epic Games Store, which has certainly happened before.
But, another potential explanation is that this is a mistake and that Ubisoft will later update the page to reflect the game's launch on Steam on October 12.
With a Ubisoft Forward showcase scheduled for June 12, we'll likely get more news about the game by then.
