Junkyard Space Agency is an upcoming co-op space agency simulator that the developer said is like a scrappier, multiplayer version of Kerbal Space Program.
On the official site the developer notes they are “committed to releasing the game’s codebase as open-source under a permissive license upon its first public launch. We believe that this project is much bigger than ourselves and that what’s envisioned can only become a reality through the collective effort, knowledge, and skills of the community”.
Well damn guys, that’s pretty awesome.
