Retailer GAME Australia leaked this announcement, but now the information within the leak is official: a new Call of Duty: Black Ops map pack called “Escalation” is coming, and its hitting this May 3 on Xbox Live Marketplace. Escalation will usher in a total of four new competitive maps and a fresh zombie 
(wait, is "fresh zombie" an oxymoron?) mode map that will come loaded with a nice perk for fans: a cast of “all-new playable characters” according to Xbox Live guru and mouthpiece Major Nelson.

So, where will this pack thrust you and your fellow BLOPers? “Zoo” will take you to the grounds of an abandoned Russian zoo, “Hotel” will keep the killin’ classy on the rooftop of a Cuban luxury hotel, while “Convoy” will test your close-quarters mettle on the grounds of an ambushed US convoy, and “Stockpile” will have you WMD facility-hopping in a secret Russian farm town.
