Yemen is a great shotgun map. Turbine is indeed crappy and boring.
I would have to disagree on you about Yemen on this with the shotgun. I hate it cuz everyone camps and with a shotty you won't have the range to get them before they get you. Now Turbine is great with a shotty, imo. Since it is a campfest and there are so many places to hide that you know where they are already. By far my best map with the shotty, always get 20+ kills running around.
Oh please. Yemen is worse than Turbine. But niether are the worst. The worst is Carrier. You called that a map... get out of here. We don't even go "inside" the whole ship. --- Versus XIII is coming in 2014, BO2 will be awesome, and PS4/Xbox 720 is coming in Dec. 2013. Lightning Return will be super awesome.
