Let me give this to you straight, there are no cheat codes because this game is meant to be played online. Having cheat codes also makes the game less fun. Not only that, but there is a guide that came with it if you preordered the game. And there's no walkthroughs because the game can be played in a variety of ways. I mean there are walkthroughs, but they are not always correct since the game can change and objects and things can be placed differently.
