Im pretty sure their was a guide for this but it's been long since burried for me, would you have to find the file for it then share it? Is it some in game function i don't know about? Im asking because my pc is getting wiped and i still want a save game.
You can find the file, back it up, or share it. You can share the files through discord too by uploading the file
All Cosmoteer saved games and ship files are located in Documents\My Games\Cosmoteer. Just backup that whole folder and you won't lose anything.
