Modern Warfare 2 takes players to the snow-capped peaks of Russian mountains, across the deserts of Afghanistan and into the streets of Rio de Janeiro, and introduces a new co-operative Special Forces mode to back up the single-player campaign.
MW2 is not a terrible game. There are much better games, and there are much worse games.
I think most of the hate from the game is from the Activision hate and general anti-hype. The Multiplayer wasn't as good as it was in Cod 4 (to many stupid gimmicks,) but the single player was decent and had some sick adrenaline moments. I give it an 8. Haters gonna hate and fanboys gonna rant, but I won't be swayed by anything other than intelligent reasons supporting the general Moddb opinion that this is a terrible game.
