Just wondering how do I use the rank/level/ wpn/kill streak etc unlockers here. It says start game, then click play, then go to barracks, run hack (alt tab out then launch from desktop), so the thing opens but after I have changed stats etc where is the 'confirm' button? What do I do after Iv changed all the info? Go back to barracks and then what? Or close the hack and play a few round??
