And wow, it's a very nice game. I played the first single player mission, but then immediately went online. The amount of modes is great, and lag - for the most part - is non-existent, and I can get into a game within 10 seconds of searching.
I was playing DM all Saturday, but then moved onto team DM on Sunday. I'd definitely recommend this game if you haven't played it yet, and were worried how the online play would be with the PS3.
