I guess i'm the opposite of what you've tried so far. And I do agree that MW3 is more like arena paintball. Take two steps and you already see the enemy, and it gets too frustration. Seems like MW3 is all about whoever pull the trigger faster. Overall it's not too much different than MW2 but sick graphic and a few good things here and there. But I definitely have to give BF3 a chance before I destroy more controllers during MW3
I love the campaigns for any of the Call of Duty games, but haaaate the multiplayer..... Halo multiplayer is so much better!
