About Tetrarchy Falls

Tetrarchy Falls is an open-source, community-run continuation of the cooperative 4X MMO originally released as Rising Constellation. The game is now maintained by volunteers from the player community.

History & Credits

Rising Constellation was created by the indie studio Black Flag Games and launched in early access in November 2020. The studio later released the game's source code to the public under an open-source license, and a group of former players took over maintenance and rebranded the project as Tetrarchy Falls for its re-release.

We are deeply grateful to Black Flag Games and the original development team for the work they put into this game and for choosing to free it.
