In a surprising new announcement, Microsoft has revealed they’ve added the ability to include Steam games in your Xbox library.

The new combined “My library” on the Xbox app is now available for Xbox Insiders on Windows, letting you connect and list your Steam and Battle.net games all on the same app, making it a single launcher for those PC games.

As with any new features out first for Xbox Insiders, the rest of users on the Xbox ecosystem will have to wait until later this year for the full integration of their consolidated library. The new combined library will also be on new devices like the ROG Xbox Ally handheld, and more.

“When a player installs a game from a supported PC storefront, it will automatically appear in ‘My library’ within the Xbox PC app, as well as the ‘Most recent’ list of titles in the sidebar—making it easier than ever to jump back into your games,” said Manisha Oza, Xbox platform product manager.

Microsoft teased this is “just the beginning” of their efforts to add more competitor storefronts to the Xbox platform, with support for additional PC storefronts coming over time. As with any of these options, you can also toggle off the aggregated game library as well.

If you want to add your Steam library to the Xbox app right now, you can download the Xbox Insider Hub on PC and join the PC gaming preview ring.
