here you go guys, all saves are made by myself, I've put around 40-50 hrs into the game to get all 1000 GS.
First play through the game on easy to get all story achievements and try to get all secondary objectives, be sure to get 9000 kills in this playthrough too cause if you do all secondary objectives you'll get 9000 kills with easy towards the end of the game.
All instructions are in the folders, use them in order 1-4
I'd suggest you test the saves first on another account just to be sure, I've not tested them
