New 5 stars out of 5 review from GamePro: http://www.gamepro.com/article/reviews/207722/gears-of-war-2/
I will update the OP tommorow. The game has now an overall score of 9.6.
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
