About

FreeOrion is an open-source, turn-based 4X space empire and galactic-conquest game, built on the explore/expand/exploit/exterminate model, with scripting support that lets the community customize game mechanics and content. It requires an OpenGL 2.1-capable graphics card and runs on Windows, macOS and Linux, with releases also on Flathub and several Linux distro package managers.

How it differs from the original

The project explicitly states it is inspired by the tradition of the Master of Orion games but does not try to be a clone or remake of that series or any other game.

Getting started

Install the native Windows or macOS installer, a Linux distribution package (e.g. apt, dnf, pacman), or the Flathub build; Linux/Unix users can also build from source following the project's build instructions.
