Do you believe digital storefronts should guarantee game compatibility regardless of changes to anti-cheat software?
Ubisoft has implemented new kernel-level anti-cheat software for its game For Honor, which effectively bans players on Linux and SteamOS. The move was made as the developer introduced new competitive modes to the title.
Why it matters
Ubisoft blocked these operating systems because it could not code the anti-cheat security measures to function with open-source kernels. This change restricts the ability of players on platforms like the Steam Deck to participate in the game.
The Standard edition of the game is currently discounted by 90% on both Steam and the Epic Games Store. Additionally, the Gold and Ultimate editions have received 85% discounts on Steam.
The players
Ubisoft
Ubisoft is a prominent French video game publisher and developer known for major franchises such as Assassin Creed and Far Cry.
The details
The kernel-level anti-cheat was introduced alongside new competitive modes, creating a security wall that rejects open-source kernels. While Linux and Steam Deck users are now locked out, Ubisoft is concurrently offering the Standard edition of the game for free via its own digital store.
Timeline
September 28, 2026: The free access period for For Honor ends on the Ubisoft Store.
Season Trajectory
This move marks a departure from broader industry trends that have sought to improve compatibility for handheld gaming PCs. It limits the total player pool for the new competitive modes by excluding the growing segment of gamers using Linux-based systems.
Players currently relying on SteamOS or Linux can no longer launch the game, effectively ending their ability to compete. Users who wish to keep playing must switch to a Windows-based environment or forfeit access entirely.
The takeaway
Gamers utilizing open-source systems should verify anti-cheat compatibility before investing time in new competitive titles. The incompatibility demonstrates how security measures can unintentionally fracture the player base across different hardware platforms.
