Ubisoft Drops For Honor Linux Support, Steam Deck Loses Out
For Honor is about to become one less reason to carry a Steam Deck. Ubisoft is ending For Honor’s Linux support on September 10, 2026, when a new anti-cheat system takes over, according to Steam Deck HQ. That date hits SteamOS where it lives: Proton can translate the game, but anti-cheat is not a translation problem—it is an approval problem.
This isn’t a badge change to shrug off. For Honor’s daily loop is matchmaking, seasonal progression, and online duels. When a publisher drops Linux support for an online-only fighter, Steam Deck owners don’t just lose a compatibility label. They lose the supported route into the game’s multiplayer world.
The Anti-Cheat Wall Windows Handhelds Don’t Need to Climb
Ubisoft’s move is a reminder that For Honor’s September cut is not a performance failure. It’s a security architecture decision. Modern anti-cheat systems often demand deep control over the operating system, and running them through Proton’s compatibility layer creates a support burden many publishers won’t accept — the same wall that locks Steam Deck players out of Marvel Tōkon Fighting Souls. The Windows-native ROG Ally, Legion Go, and other handheld PCs are outside that blast radius, which makes the divide in handheld gaming less about GPU wattage and more about which OS the publisher wants to protect.
‘Verified’ Is a Snapshot, Not a Promise
Steam Deck Verified has always been a check at one moment in time. For Honor’s existing Linux access was built on compatibility work that Ubisoft is now discarding. The game doesn’t have to be badly optimized or poorly tested to lose Deck support; it just has to change its anti-cheat. That’s the structural weakness of choosing a handheld for online multiplayer. Communities can patch visual bugs, but they can’t patch away a publisher’s anti-cheat decision when the service itself changes on that date.
Watch the Anti-Cheat Choice Before Your Next Deck Purchase
If you buy online-focused games for SteamOS, For Honor’s September 10 should be part of your purchase math. Ask whether the developer publicly supports Linux, whether its anti-cheat vendor has a Proton-compatible mode, and whether the title depends on day-zero security updates. If the answer is vague, assume the compatibility can be revoked. Windows handhelds and dual-boot setups are the fallback, but the cleanest fix is to treat For Honor as the latest proof that on Steam Deck, always-online access is rented, not owned.
