Ubisoft Will Block For Honor on Linux and Steam Deck From September 10

Ubisoft is ending Linux and Steam Deck access to For Honor multiplayer from September 10, citing concerns about its ability to provide effective anti cheat protection on the platform.

The change affects players running the game through Linux based systems, including SteamOS on Steam Deck. For Honor currently uses Easy Anti Cheat on PC, but Ubisoft says it cannot deploy the level of protection it considers necessary on Linux.

The company says the decision is intended to support a fairer competitive environment. It has also left open the possibility of restoring Linux support in the future if its anti cheat approach changes.

Steam Deck Players Will Lose Access

For Honor launched in 2017 and continues to receive seasonal updates, so the Linux restriction affects an actively supported multiplayer game rather than an older title approaching the end of development.

Steam Deck can run many Windows games through Proton, Valve's compatibility technology. This has greatly expanded the number of PC games available on Linux based systems, but competitive multiplayer remains more complicated.

Anti cheat systems need to detect software that alters game behavior, and support through compatibility layers can differ depending on how individual developers configure their games. Easy Anti Cheat has supported Linux, Wine, and Proton environments for several years, but that technical support does not automatically mean every game using it will allow Linux access.

Ubisoft says it cannot currently provide meaningful protection for For Honor on the platform. As a result, the company has chosen to block access rather than continue supporting multiplayer sessions under conditions it considers less secure.

The restriction also means Steam Deck owners who previously accessed the game through SteamOS will no longer be able to continue playing normally after the September 10 change takes effect.

Ubisoft Could Reconsider the Decision Later

The company has not described the removal as necessarily permanent.

Ubisoft says it plans to continue investigating ways to improve its anti cheat protections and could reopen the platform if it finds a workable solution. No timeline has been provided for such a change.

That leaves affected players without a clear indication of whether Linux compatibility will return or what technical improvements would be required.

The situation also highlights an ongoing limitation for Steam Deck and Linux gaming. Many single player games work well through Proton, but competitive online titles often rely on anti cheat technology that can create additional compatibility and security concerns.

For Honor is also not the first major multiplayer game to remove Linux access over cheating concerns. Apex Legends dropped support for Linux and Steam Deck in 2024 after its developer said the platform required a disproportionate amount of anti cheat attention compared with the size of its player base.

Ubisoft is now taking a similar approach with For Honor.

For players who use Windows, the change should not affect normal PC access. The restriction is specifically aimed at Linux based environments, including SteamOS.

The decision may be disappointing if you purchased or regularly played For Honor on Steam Deck, especially because the hardware is capable of running many demanding PC games through Proton. In this case, however, performance is not the problem. Ubisoft's concern is maintaining anti cheat protection across the multiplayer environment.

Unless the company changes its position, Linux and Steam Deck players will lose access to For Honor multiplayer on September 10.
