Developers of the Heroic Games Launcher have announced Xodus, an open-source project aimed at enabling access to PC Game Pass on Linux and macOS. Launched on August 10, 2026, Xodus has successfully addressed Xbox identity authentication and the decryption of MSIXVC packages, allowing local play of Game Pass titles for Linux and macOS users. Currently, the only way to access Game Pass on non-Windows devices is through Xbox Cloud Gaming, which requires a Game Pass Ultimate subscription and introduces latency.
Xodus employs a layered architecture, including an Xbox Authentication Library (xal-rs) for managing Microsoft account sign-ins and license verification, and a reimplementation of the xgameruntime.dll for license checks and Xbox service access. The project can retrieve MSIXVC game packages using a valid Game Pass subscription and decrypt executables for local storage. However, it does not yet support UWP-based titles and lacks a user-friendly interface for general users.
The project is under pressure due to Microsoft's upcoming transition to the MSIXVC2 package format, which Xodus does not currently support. Xodus is in early development with only a command-line interface available, and the team is working on emulating the GDK Gaming Services layer necessary for game initialization. The project is legal as it reimplements Xbox runtime behavior without enabling piracy, but it faces risks if Microsoft alters its authentication infrastructure.
