I have been playing Call of duty since 2004 played (COD,1,2,3 not much was only for playstation,4 which is MW1,5 world at war,6 MW2,7 blackops 1,8 MW3,9 and the last one black ops 2.
activition has done great job all those years,had some fails like in COD 3 (only for playstation,that was stupid),but COD BO 2 the last one,was surprising in my opinion everyone saw the bus and the zombies was amazed and thought that the game will suck and the zombies will be great,from my experience and as I think what happened is the opposite,the zombies sucked and the game was just great.
But I find some bugs like :
and another bug which is sometimes when they want you to look at a window you'll see your player face reflection on the window and when you look without them asking you to you won't see it.
for conclusion great game (specially riding the horses and robots & new airplanes&weapons lots of new ideas)
waiting for MW4 now,tell october or so.
