I just got it and I have to say..
This is the worst call of duty, or perhaps game, to date. I've only been playing for 2 hours and I can't stand it anymore. Yeah, Modern Warfare 2 was bad, but atleast it was fun for a longer time than Black Ops.
The hit detection is flat out terrible, I have awesome connection but my bullets seem to curve away from the guy I'm shooting. Second, everyone just runs around quickscoping or using ak74 and m16 while dropshotting. The only thing I can compliment Treyarch for is the customization and zombies.
You can criticize this post all you want. This is my opinion.
