The maps are up in rotation when playing. I believe there is still a separate escalation playlist.
If you are playing a private match where you can choose a map, look at the very top of the screen, there should be a tab that says dlc or something similar. It will open a new page with the new maps listed.
I'm also experiencing this problem, i have the escalation pack and today black ops came out with an update and i can no longer find my escalation option tho i am still able to play call of the dead. If this is something like where they tgake away a map that
weve all paid for in order to focus on new maps then thats effed up and should be addressed they make soo much money already off of these dlc's that they shouldnt be beating us out of our purchases.
I have another problem. I have deleted the title update 9 in order to remove patches for BO zombies, and i have also been playing on 'call of the dead' on the escalation map pack, but as soon as i deleted the title update i could no longer play call of the
dead and the other multiplayer maps had vanished yet on my hard drive there is still 'Escalation [en['. Anyone know what i can do to play call of the dead again, please?
