Yeh. Berlin Wall yields a LOT of ghost pro/galil silenced badkids. but I still think the new maps are all good. they break from the drudgery of the old maps by adding death-spots, destroyable bridges, zip lines, and some hectic a$$ gameplay (stadium)...
I am really hoping CoD MW3 developers are considering a destruction engine like BFBC2 has because that would beef up CoD in a serious way. And for bonus points, I'd like to see them make the sniping like BFBC2 also. Then sniping actually takes some skill. [not that I'm' implying that cod snipers are weak or anything, but if you've ever played BFBC2 then you know what I'm talking about with the sniping. It's MUCH harder than it is on CoD]
