Where are the saves located?

[NO THIS IS HATTRICK]

And how do I backup my save?
Do I just navigate to HKEY_CURRENT_USER\Software\NoBrakesGames\Human in regedit and export the entire registry folder?

[Primal Fear]

Yes, the save games are there so normally that should work.

[Eep²]

No save games in that registry entry; just settings.
