I re-bought this game on PS3...GOTY Edition...when it comes to multiplayer (level 7 or something right now) I feel like I'm doing a lot better than when I first owned the game. But I still can get pwned impossibly fast. Is it in the weapon they use? Are there cheaters? How does the auto-aim sometimes work against other players and sometimes not? I want auto-aim completely off for everybody when it comes to engaging real people. That's how it ought to be. Is that a certain Free Roam difficulty setting, or is it all on each player's options?
