Since you're using MPH, you can add and find your friend code on the same menu.
Also, you'll get better. I sucked at MPH when I first started. Mind you I still suck. >.>
Yeah im play MPH, what is Lag?
What i dont get is I couldnt shoot him, because he was in the wall, and could shoot out, but i couldnt shoot in......
So he cheated? That can ruin the whole game though
