I kind of used Demons method after my game failed to pop the minikit cheevo with a few exceptions. I ran through the first 10 or so missions on story mode before i saw his post. I then went back and freeplayed them all for the kits. I then did demons method to the letter and the cheevo popped on HostageCrisis after getting my 2nd minikit.
Thanks Demon, for allowing me to finally put this game in my completed file.
