Ahead of its fourth act, released back in July 2016, Kentucky Route Zero only had one slot. When you start the game ends you will find three, numbered zero in pairs. If you've played it on Steam, be aware that Steam Cloud doesn't work, which saves stored games history. The same goes for the version available through GoG and Itch.io. However, there is a file to save. According to co-creator Jake Elliott, you can safely move it between any game version on Linux, Mac and Windows PC and choose where to turn.
"The old save files should be 100% compliant in the last game," Elliott wrote Polygon in an email. "They are really xml files and they can be used with cross-platform […] The original episodes have not changed without bug fixes, localization, and other technical improvements."
That means the hardest part of coming to your old save is probably claiming your old computer. If you manage to breathe life into the old beast the files you want will be inside your document folder, under KentuckyRouteZero. They are named "save.krz", "save-1.krz", and "save-2.krz" respectively. Just cut and paste those into the same folder of your chosen platform.
Of course, this workspace is not available for all game types. Those playing on Nintendo Switch, PlayStation 4, and Xbox One – new models starting in Jan. 28 – they will need a fresh start.
