So some of you might be bored after rank-hacking and an extremely high and obvious hacked KDR. Im here to show you how to reset your ranking PERMANANTLY.
1. Open your steam folder (google where that is)
2. (steam>steamapps>common>call of duty modern warfare 2>players)and delete all the STAT files.
3. Go to the steam folder again and click userdata.
4. Go through all the numbers, go in the 'remote' files and delete all the files in there.
5. Play and level up, and it should store to steam cloud.
