About this project
OpenCE ports an early Xbox Halo engine to SDL3 and modern OpenGL/OpenGL ES/WebGL2 targets. This is a source port of the Xbox game, not the separate PC Custom Edition executable.

Known limitations
The foundation is an early development build. Rendering interpolation does not change the original 30 Hz simulation. OpenSauce custom-map extensions are unsupported, and debug assertions can stop a debug build; multiplayer claims remain maintainer reports.

Getting started
Choose the official release package for your OS or the Android APK. At first launch, select your Xbox image so the importer can extract maps. Custom maps have a separate custom_maps path; use the release build when following the player guide.
