a kd/r changer is not possible, as long as you don't know the amount of kills / deaths you have. if the game would be family-sharable, someone could play on other account and change the value on CE every round, for example 0 kills - first game like 20 - change to 20 (4byte). than do it over and over again, on another cheat engine exe do the same with deaths or document the deaths in for example editor.txt (sorry 4 bad english :P)
I think they fixed this method. I can't unlock the camos for launchers. I'm destroying the UAV's,CUAV's and still it gives me the standard points. As for howitzer, is impossible to get a longshot...holy molly. Could you find a method to unlock the longshot camo especialy? Thanks !
