You might try this,
C:\game install here\SteamLibrary\SteamApps\common\Men of War Assault Squad 2\resource\map\single
I have Men of War original, not the Assault Squad 2.
When I open the resource folder, the following options I have are
Entity
Interface
Game Pak
Interface_Euro Pak
Music Pak
Red_blood Pak
sound pak
Texture Pak
Video_Common Pak
Video_eng Pak
Voice_eng pak
No map to click on.
Entity folder opens to
e1 pak

e3 pak
Interface opens to
an image of Men of War logo with title splash under it.
I checked all the pak folders with winrar
None of them led to anything related to maps except the game pak
Game pak opens to

I have a saved folder here named 123 and I don't see it on this list. I checked Single multi, editor_tut and I can't find my saved map.
