I'm using this method but it's only a visual change... all weapons past my old rank are still locked out ingame, and my rank is still no different in the menu/barracks. Afaik there's no hack on here for the latest SP client, and I've tried using a players2 folder/profile which doesn't work on steam, only with a cracked copy of the game (I need to use steam because it has all the DLC). What am I doing wrong? Should any of these methods work?
