Anyone interested in modding Medal Of Honor Warfighter might find this usefull. I have extracted my Gamesave and my GPD.
I have just completed the 5th mission on campaign. Not played no multiplayer yet.

I found the campaign progress stores on the GPD file, like what missions you have completed ect. Could be interesting
Hope this helps. :)
