Which one should I get if I was to get it. I was thinking of getting it off steam if I could and try to play it online with who ever could deal with my poor shooting skills.

If I can't get it that way, then I'm going to probably get it for the ps3, as I'm better with a controller then I'm with mouse and keyboard.


So if I do get it which one should I get, and what do people play more one, or two?
