Xbox Game Pass has never really worked on Linux beyond laggy cloud streaming, but an open source project called Xodus is trying to change that. Earlier this week, replying to a thread on Reddit, Paweł Lidwin (imLinguin), project lead of Xodus, confirmed that the hardest parts of running those games on Linux, Xbox authentication, and game downloads are already working. The project is attempting to reverse engineer Xbox's entire authentication, licensing, and delivery pipeline well enough to run Xbox on PC and Game Pass titles on Linux. You see, modern Xbox PC games run on Microsoft's Game Development Kit, or GDK, and ship as encrypted⁣ MSIXVC packages. Game libraries on Steam, GOG, and Epic Games already run well through Proton and Heroic, but Xbox PC and Game Pass titles have been locked to Windows or laggy cloud streaming until now.
