Thanks, at least I know it now. But I see someone else has uploaded a save already.
Try it my way. You don't need any special program for that. I am using Total Commander as file manager. Go in game, do something that will cause it to save changes, like customize your wanzer or finish a short level and search for files in documents folder that has been changed recently. There is an option for that when you search for files in Total Commander.
try at the following location
file in there is your savegame
this is for x64 Windows 7
I am wondering can you give an example for the foldername? I had searched the whole Appdata in window 7 can't find any saves for it. BTW i am using Steam.
