Call of Duty Black Ops Escalation is the 2nd DLC for Black Ops. It features 4 new maps and a new installment in the zombie series "Call Of The Dead".
Zombiesplay as the zombie-killing dream-team of Sarah Michelle Gellar, Robert Englund, Michael Rooker, and Danny Trejo against a new and unnerving zombie menace. Set in a mysterious, ice-covered, remote Siberian island and inspired by legendary writer and director George A. Romero, a group of four fearless explorers fight for their lives amidst an army of bloodthirsty Soviet zombies.(Taken from the website).
I had quite fun playing this map. George Romero follows you around the whole time and can get annoying. If you shoot him or get hit by him he gets mad and you have to lead him to water which if you stay in to long you freeze to death. This map is more of a challange than most maps. Includes new weapons and a new perk.
MultiplayerIncludes Stockpile, Zoo, Hotel, and Convoy
I havent played much of the multiplayer. The only map I didnt play was Convoy. I was kinda dissapointed in the multiplayer maps besides Zoo. Hotel is an okay map to. Stockpile is more of an objective gamemode map. Like I said I can't say much on the maps.

Is it worth 15$? Yes. Let me clarify this. If you have alot of friends who play and you enjoy the COD series it is.
