Xbox PC games face challenges on Linux due to Microsoft's proprietary Game Development Kit (GDK), affecting performance and Game Pass functionality. An open-source initiative called "Xodus," developed by the creators of Heroic Launcher, aims to reverse engineer components for Xbox PC games to run on Linux, focusing on modern titles using GDK and MSIXVC packages, but not older UWP games. Microsoft has recently brought four original Xbox titles to PC and may release Xbox 360 titles next year with an emulator, though it is unclear if they will use the GDK framework.
