i thought the story was cool... not as strong as some of the other call of duties, but when i explained the plot to my wife after i beat it, she told me that it sounded ridiculous like a soap opera... to each his own i suppose... also in regards to the story, veteran mode is difficult like all of the COD's, but i'd say it is easier than COD 4, COD MW2, and COD WAW...
the online seems pretty cool, but i don't like that you have to buy stuff to unlock it (it's all fictional money that you earn in game)... i'm stingy with money, and even though you earn plenty of money i still feel semi guilty making purchases on anything other than a red dot scope
i don't really anticipate getting into zombies that much, but maybe when people get board of the regular multiplayer they will get into zombies... i haven't played zombies much yet though so i can't really review it... i just played enough to get a few achievements...
