modern warfare 2 is one of the most hacked games of all time, since buying it in november there have been countless hacked lobbys hacked accounts and glitches. and the matchmaking in multiplayer is a joke. everyday i get messages sent to me saying there is a 10th prestige lobby and they want 2100 microsoft points. ive reported everyone ive recieved yet i still get them. if activision dont do something about it soon i will simply sell the game as so far it has been a total waste of money, dont get me wrong the game could be good if there wernt so many problems with it. and with updates come more problems. when i downloaded the stimulas pack i cound no longer play online games nor the map pack i had just purchased for 1200 microsoft points. they gave me 7 days free xbox live as compensation. what a joke. if your thinking of buying modern warfare 2 then my advice is dont. buy battlefield bad company 2 instead it wont frustrate you half as much.
