I've been trying to get into a match for about three hours now and I've only succeeded once. It was co-op and it froze after 5 minutes.
Pros:
Guns have more kick
Cons:
Graphics actually look worse than uncharted 2
Friendly fire is back (WHY???!!!???)
3D is terrible
Maybe I will have more good things to say when I actually get to play more matches but right now it seems pretty mediocre. I think ND should just focus on single player, that is their strong suit.
