Hi. Excuse me if I seem like a noob, i'm new to the game modding community.

I'm here for Call of Duty MODs only, and this thread will focus on MW2, and other general questions.

Any answers are greatly appreciated

Q1: What is bypassing? Never heard the term before :$

Q2: Last night I was modded to 10th Prestige rank 70 by someone. It's a great mod and i'm greatful, but I don't have all the challeneges, titles, emblems etc. Is there anyone who hosts a challenge lobby like that? Would I have to bypass to get into one? I really want to get in

Q3: Can I be banned for joining these lobbies? Not really worried about it, it's just out of curiosity.

Q5: These "infections," for example unlimited UAV.. how would I go about allowing myself to infect myself and others? Would I have to jailbreak my PS3?

Thanks to whoever answers these.
You don't have to answer them all, just whatever ones you can!
