Summary: This game is the same as every other Call of duty by IW (since COD4). SPOILER ALERT, but you are on the ground, dazed, on the final mission. In MW2, you were on the ground on the final mission. In MW, you were on the ground in the final mission. Spec ops is kinda okay, but MW2's was better. Survival mode was a ripoff of zombie and some aspects of Mass Effect, Uncharted, etc. The multiplayer is the worst though.
Summary: Loved the (really short) single player campaign. Hate the Multiplayer. More of an expansion to MW2 rather then a new game. Do yourself a favor, and rent it before you buy it. I prefer BF3 over this.
Summary: I've played Call of Duty for as long as I can remember. Let me take you back in time the year is 2007 and Call of Duty 4 has just come out. I am blown away by every stunning feature in the game. It has a whole new feel that I've never felt in videogames before. Fast foward to the present. Modern Warfare 3 fails and it fails hard. I'm not hating on this game because it isn't a bad game the only problem is that it's exactly like, almost identical to it's predecessor MW2.
