Ya important thing to point out, when you go on MP, turn trainer off, because it might happen some people forget SIGH, so i was really scared!, than im like OMFG!!! gotta right away stop it!, fiwf, just a reminder be careful and pay attention turn it off before MP, or ur gnna sync out eveyr time.... good thing noting bad happened!
Multi-player is for the sports minded, for those who love to compete and win because they work hard and are "smart" in their strategies. Don't be one of those steroid user "athletes" they get caught and banned and worse. If you cant play MP and not cheat then just stay with the missions and cheat your heart out. There are a lot of good people online that have given me pointers (after whooping me bad) and I have loved the experience. Bear in mind I am not a big MP guy.
