I played a couple online matches at a friend's house a few nights ago on Xbox 360. It was... meh. I can't really get into the whole auto-aiming thing (on PC we call that "hacking", haha) and using a console controller for a first-person shooter. I did like the over/under shotgun and the RC carbomb thing though!
I'll buy a copy for PC in the next few days and let you know what I think about that version.
