What it is

OpenJK is a community effort to maintain and improve the game and engine powering Star Wars Jedi Knight: Jedi Academy and Jedi Outcast, while keeping full backwards compatibility with existing games and mods. It does not intend to add major features or rebalance the game: it aims to improve stability and performance, support more hardware (x86_64, Arm, Apple Silicon) and systems (Linux, macOS) and provide a clean base for modifications. It is licensed under GPLv2.

According to the project, Jedi Academy is stable in single player and multiplayer; Jedi Outcast works but needs attention and its multiplayer is not supported (JK2MV is recommended). You need Jedi Academy installed. GigaROM hosts neither the engine nor the game.

What you need

Your original copy: Jedi Academy installed (for example from Steam, Amazon or GOG). The project does not include game data.
  • Windows, Linux or macOS.
  • Jedi Academy installed (for example from Steam, Amazon or GOG).

How to install and run it

  1. Download the latest build for your system from the official page (“Go to official project” button).
  2. Extract its contents into Jedi Academy’s GameData/ folder (on Steam, steamapps/common/Jedi Academy/GameData/).
  3. Run openjk.x86.exe (Windows) or the matching Linux/macOS executable.

Current limitations

  • Jedi Outcast works but needs attention and its multiplayer is not supported.
  • The latest published build is from 2023.

Port or emulator?

If your computer does not meet the requirements, you do not have the exact version the port asks for, or you prefer the classic route, you can play the original with a console emulator: see emulators and its install and setup guide.
