Enthusiasts are working on the Xodus project, an unofficial open-source initiative aimed at enabling Xbox PC games, including those from Game Pass, to run on Linux and Mac systems. The project is a reverse-engineering effort that allows users to log in, download packages, and obtain game licenses for Xbox titles. The team has experience from previous projects like the Heroic Games Launcher and aims to support a wide range of Xbox games formatted in GDK and MSIXVC. While Xodus can download and run these games, additional patches may be required for optimal performance.
