For back-up purposes, here i will list the game’s save location. The game’s save files are located in:
You can also save and import character customization to save time in character creator between different games. The path should be:
c:\Program Files (x86)\Steam\steamapps\common\Kenshi\data\character\bodies\export
This path is for Windows 10 64bit. It goes without saying that this is the Steam version of the game. Game installed from elsewhere may or may not be in the same directory.
