Microsoft is providing an update on its support for Valve’s Steam Deck today. Most Xbox Game Studios titles will run on the Steam Deck, but Microsoft says Gears 5, Halo: The Master Chief Collection, Halo Infinite, and Microsoft Flight Simulator X are unsupported. These titles don’t work on the Steam Deck due to anti-cheat systems, and it’s not clear if they’ll ever be supported in the future.

Microsoft has marked eight games as “Verified,” and six more as “Playable.” The difference between the two can be something as small as a warning appearing or even having to invoke a virtual touchscreen to enter text during a game. While some are only on the playable list right now, they could soon progress to verified status.

Microsoft’s list only covers Xbox Game Studios titles currently available on Steam, but you can now install Windows on the Steam Deck to access Xbox Game Pass games. Valve has just released Windows drivers, so the option is open for Steam Deck owners to switch over. Valve CEO Gabe Newell welcomed Microsoft to launch Xbox Game Pass on Steam last month, saying he’s “more than happy to work with them to get that on Steam.”
