OpenJK is an effort by the JACoders group to maintain and improve the game engines on which the Jedi Academy and Jedi Outcast games run on, while maintaining full backwards compatibility with the existing games. This project does not attempt to rebalance or otherwise modify core gameplay.

The goals of OpenJK are to:

Improve the stability of the engine by fixing bugs and improving performance.
Provide a clean base from which new JO and JA code modifications can be made.
Make available this engine to more operating systems. To date, we have releases on Windows, Linux and macOS.

The OpenJK JKHub sub-forum is the best place for support queries, discussions, and feature requests. Bug reports and major issues should be reported as Issues on GitHub.
