I played some last night with a friend from another board, and without his help I would still have no idea what I was doing. Once I got the hang of it however, I started to have some fun. I've also noticed a severe lack of communication during games. It's like the amount of players online is so large that no one feels comfortable talking to all of those strangers or something. Very different to Gears Of War where with only four to a team everyone is relaying instructions/requests back and forth.
I'm UltraMav on PSN if anyone wants to play.
