This was my 1st PS3 game, and I regretted it. But lately, I am getting really into this. My lil brother forced me into this, because he wanted to play, but I wouldn't let him (he is 7th grade, plus I gave him my xbox right after I bought this PS3!). So I always have to play on splits screen. And I noticed that there is a huge difference from split screen to one player. It's sooo weird. I totally lose my control. That becomes a big problem for aiming.
On another note, which guns do you guys like or use the most on MP?
