Key facts
- The open-source Xodus Nexus project allows Steam Deck users to natively download and run Xbox Game Pass titles and other Xbox PC games directly on their devices.
- Xodus Nexus is an unofficial, experimental project not endorsed by Microsoft or Valve, and users are warned to proceed at their own risk.
- Xodus Nexus is built on top of the Xodus project, an open-source reverse-engineering effort launched on August 10, 2026, by Pawel Lidwin and other contributors.
- Xodus Nexus provides a graphical user interface with features such as browsing the Xbox store, managing download queues, and automatically adding games to the Steam library with artwork and shortcuts.
On Oct. 20, 2026, the open-source Xodus Nexus project released version 0.3.8, a launcher that lets Steam Deck users download and run Xbox Game Pass titles natively without installing Windows or using cloud streaming. The update adds detailed game pages with descriptions, categories, and screenshots, plus display of Xbox achievements, playtime, and recent activity. Version 0.3.8 also introduces a graphical interface for browsing the Xbox store, managing download queues, and automatically adding games to the Steam library with artwork and shortcuts, replacing the command-line tools of the original Xodus project.
The launcher supports over 65 Game Pass titles, including Forza Horizon 5, Halo Infinite, Gears of War: E-Day, and Minecraft Dungeons 2. The GitHub compatibility list for Xodus Nexus also includes Valor Mortis and No Man’s Sky as playable on Linux systems. However, compatibility is uneven, and games such as ARC Raiders and The Witcher 3 fail to launch.
Xodus Nexus is built on the Xodus project, an open-source reverse-engineering effort launched on Aug. 10, 2026, by Pawel Lidwin and other contributors. The Xodus project’s GitHub organization describes it as an open-source reverse-engineering effort to make Xbox PC games, including Game Pass, run on Linux and Mac systems. The project has already reverse-engineered Xbox identity authentication and the decryption of encrypted MSIXVC game packages.
The technology reimplements Microsoft’s authentication pipeline with components such as xal-rs, an open-source replacement for the Xbox Authentication Library, and forked versions of Wine and Proton that carry Xbox-specific patches. Additional repositories provide a replacement for the Windows-only xgameruntime.dll and handle parsing and decryption of MSIXVC containers. The core Xodus repository, written in Rust, had drawn 47 stars and four forks on GitHub as of August 2026.
Development spans several repositories under the GPL-3.0 license, with the community coordinating through an active Discord server. Pawel Lidwin stated, “Xodus can already log into Xbox accounts, access Microsoft’s store, and download games on non-Windows operating systems.” The project’s checklist confirms completion of device registration, license parsing, and MSIXVC decryption.
The developer still faces major technical hurdles, including on-demand decryption of individual game executables, support for the newer MSIXVC2 format, and rebuilding the Xbox Gaming Runtime for Wine. The launcher also cannot bypass proprietary anti-cheat systems used by titles such as Call of Duty and Destiny 2.
The Xodus project targets newer titles built on Microsoft’s Game Development Kit, or GDK, and packaged in the MSIXVC format. The GDK contains three components that tie every PC Game Pass title to Windows: Xbox identity authentication, encrypted MSIXVC game packages, and the proprietary Xbox Gaming Runtime. The Xodus project has successfully reverse-engineered the Xbox identity authentication and the decryption of encrypted MSIXVC game packages, which sit inside the GDK.
Two additional Xodus repositories fork Valve’s Wine and Proton, carrying Xbox-specific patches into the compatibility layer. Getting decrypted games to run requires rebuilding the Xbox Gaming Runtime for Wine, with the runtime service layer communicating through a Unix domain socket named xodus.sock.
Because the project targets the newer GDK and MSIXVC pipeline, older Universal Windows Platform titles are likely unsupported.
The Xodus project’s documentation names Gears of War 4 and early Forza Horizon releases as titles likely to stayunsupported. Minecraft Bedrock Edition and backward-compatible Xbox titles are listed as future targets in the project’s FAQ, pending resolution of the pipeline. No release date has been announced for the project, since runtime emulation remains unsolved and no current build can run a game from beginning to end.
Xodus Nexus is unofficial and not endorsed by Microsoft or Valve, and its documentation warns users to proceed at their own risk because it may contain bugs or incomplete features. The software carries the GPL-3.0 license and spans multiple repositories.
Installation requires switching the Steam Deck to desktop mode, downloading the latest release from GitHub, and installing dependencies like Visual C++ Redistributables. Google Chrome is recommended for optimal stability when logging into a Microsoft account during Xodus Nexus installation. After logging into a Microsoft account, users can add the app to the Steam library for launch in Gaming Mode, though some dialogs may require a mouse or touchscreen.
The developer, who does not own a Steam Deck, is testing in a virtual SteamOS environment and is seeking a used unit for physical testing. Anyone with a used Steam Deck to sell can contact u/Embarrassed-Hall-617 on Reddit. The launcher supports Xbox cloud saves and sign-in for compatible games, and it can also run Xbox Play Anywhere titles and other Xbox PC games beyond the Game Pass catalog.
Steam Deck owners currently can only access PC Game Pass through Xbox Cloud Gaming, which requires a Game Pass Ultimate subscription priced at $22.99 a month as of April 21, 2026. Xbox Cloud Gaming adds streaming latency and requires a stable internet connection for every session, unlike Xodus’s model of local download and native play.
