OMG what a sick ass game. Got it today (got PS3 today too), holy shit, what a masterpiece it is so far (I'm in the snipers with laser sights section), the graphic is breaktaking, but the action and how HARD it is even when you play in the easiest mode, makes is such an epic game. I mean, I'm a fairly good gamer in these type of games, but its like you have to re-think how you play completely. You cant be without cover for 5 seconds, or you are TOAST.
But most importantly, how ridicolously inventive and and smart the AI, they use the surroundings so tactically. I could gun down a whole squad quickly, and then be stuck on 2-3 guys for a LONG while because they were fllanking me nonstop, even the most minor of check points bits could be pain in the ass, if you didnt read carefully and play it soundly. As it was said above, no such thing as run and gun anymore, which was mainly the basis for these type of shooters.
