Microsoft’s new flagship shooter Halo Infinite doesn’t run on Steam Deck, the latest big game to be affected by draconian security measures.

It’s not just Halo Infinite, however, as the Master Chief Collection, Gears 5, and Microsoft Flight Simulator all won’t run on Valve’s new handheld. The reasoning? Anti-cheating software.

Microsoft plainly noted four of their biggest games won’t run on the Linux-based handheld PC, as most anti-cheat software won’t run on Linux – and Steam Deck’s native operating system is Linux-based. It’s also worth mentioning this also includes the single-player campaign for Halo Infinite.

News that Halo Infinite doesn’t run on Steam Deck comes alongside several other big competitors not supporting the handheld – also due to anti-cheat software. Destiny 2 won’t run on Steam Deck, as neither will Fortnite.

Halo Infinite is available on Windows PC (via the Microsoft Store, Steam), Xbox One, and Xbox Series X|S. The game is also available on Xbox Game Pass. In case you missed it, you can find our thorough review on the game here.

Valve’s recently launched Steam Deck is now available, and in three flavors: $399 (64GB), $529 (256GB), and $649 (512GB), over on the Steam store.
