most people dont post the indivual files to inject... and you cant replace entire file with old mod file because after patches it can cause errors. this is because after patch if new guns/characters etc would not be in your old files. you would have to extract your old mod and reinject it to the new file. i had this problem last patch ,, the new scope was all wack because i used my old mod file. i figure to be on the safe side since i am not sure what all they change, i just mod the new files.
