Got this game the other day, love it. :)
I beat the single player campaign on normal mode today, and decided to try out multiplayer. The first game I joined was in Chicago, and there were 58 players in it. I was blown away by the amount of action there could be in an area at once, and how much fun Hedgehog Grenades can be when thrown into a hoard of 20+ players. Absolutly fantastic game, and if you have a PS3 you should really consider getting it.
Discuss your thoughts on the game.
EDIT: Just going to post my PSN if anyone wants to add me. "bighatch65" (Was my fathers till' I started playing with it, thus saving my games to it)
