OpenJO for Jedi Outcast

OpenJO is the Jedi Knight 2: Jedi Outcast version of OpenJK. All of the below is copied from the OpenJK page, but it all applies. Installation instructions should still apply to JK2, with different folder names for the games. This is for single player only. For multiplayer, please see JK2MV.

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

Our aims 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.

If you need help, the JKHub sub-forum is a better place for support queries, discussions, and feature requests.
