Project Summary
Master of Orion-inspired turn-based game of epic space strategy that builds on the classic '4X' model by incorporating the nation-building elements of games such as Europa Universalis 2 and a versatile tactical combat engine.
While its modular design allows for a significant degree of customization of the game engine and the story elements by the community.
The FreeOrion team is dedicated to the construction of a living, breathing universe in a 'grand campaign' model.
