Black Ops is now 4 months old, by the time W@W was 4 months old there was hundreds of zombie maps out, and thousands out now (the ZCT maps rule, and are in fact light years ahead of the official maps).
So yeah $15 for 1 new zombie map and more terrible MP maps is a fucking disgrace. At least deliver on the modtools that where promised and we'll make our own maps (a lot of which will be better than Treyarch's maps).
I can't speak for the absence of modtools, as I'm sorry to say, but I've gotten more and more used to not getting them these days. I know it doesn't make it right, but that's the way it is.
$15 might sound like a lot for one zombie map (and four multiplayer maps that I probably won't play very much atall), but if I get even half the time from this new map that I've gotten from Kino Der Toten, then it'll have proven itself to have been pretty good value for me.
I played several of the community zombie maps that had been made for World at War, but none of them really did anything for me. Not compared to the official maps, at any rate.
