I haven't gotten them and will not get them. I fell for that last time with the MW map packs. They sucked and from what I understand the only way to get rid of them is to uninstall MW completely? Nooooooooooooooooo!
I only got to play the 2 old ones and 1 new one, but the only thing that bugs me is that you cant select to play just team deathmatch like I like, but instead you rotate every game version they have, and I'm horrible at all but team deathmatch and S&D...
