Linux save files path?

[Player]

Hi. I need to know the save files location on Linux. (I am using Linux Mint 17.2 Xfce x64 based on Ubuntu 14.04).
I thought the saves are on the same directory that the game is

/home/username/.local/share/Steam/steamapps/Overlord

or

/home/username/.local/share/Steam/userdata/<steam_id>/11450

but there is no folder named "11470" or "11450" (http://store.steampowered.com/app/11470)
only

/home/player/.local/share/Steam/userdata/<steam_id>/760/remote/11450

, but that is a Steam remote place where the screenshots are saved.
I want to make a backup, because time to time I have a hanging game - the minions are moving but my character is walking on the same place like a "moonwalker". The game is not responding, even cannot launch the Menu or even the Steam in-game overlay.
Have anyone experienced this or I am the only one? Thanks!

My guess, the correct answer is:
~/.local/share/vpltd/Overlord/GameDocuments/Overlord

You should archive all of it, since this directory contains the following subdirectories & files:
... /Profiles
... /Save - <ProfileName>
... /Save - <ProfileName>- Expansion
... /Settings.dat

Yes you are right! My errors were - on Thunar file manager Search function the hidden files were disabled and the file and folder order was not by name, but by Date Modified.
Thanks a lot! I have made the backup.
