Spacebase DF-9

Spacebase DF-9 is a space simulator video game developed by Double Fine Productions. It was prototyped during Double Fine's open Amnesia Fortnight 2012, directed by JP Lebreton. After being released as an open beta on October 15, 2013, it was officially released on October 27, 2014, for Microsoft Windows, OS X, and Linux. After the official end-of-life of the game in May 2015, the community took over the development based on an open-source code fork. The community fork of this game has also since been abandoned, the last update Patch v1.09 Unofficial - Jan 16, 2023 marking the end of community-accepted contributions.
