If you asking about the map It's on Black Ops, but you have to buy it. Sorry...The PC PS3 and Xbox 360 Version of Call of Duty Black Ops can purchase the Escalation DLC that includes Call of the Dead. It is not available to other Black Ops versions or without purchasing the DLC for $15
it comes with the escalation map pack so 14.99$
Call of the Dead is from the Escalation map pack and is only sold to the PS3 PC and Xbox 360
Call of the Dead is not even available for the PS3 until the June 3 2011 release of the Black Ops Escalation map pack which includes the zombie map Call of the Dead. It is not free and will cost $15 for Escalation
Someone buys it for you for $15 and still you can only get the Escalation map pack that has Call of the Dead as one of the 5 maps. You can not get Call of The Dead without getting the Escalation map pack and it is sold for $15
You buy the Escalation map pack for $15 and get the Call of the Dead and 4 other maps
Call of The Dead is merely one Map from the game Call of Duty Black Ops and can only be played when you have Call of Duty Black Ops and the Escalation Map Pack that includes the Zombie Map Call of The Dead. Black Ops is way more popular than Minecraft
Most people would say escalation
you need to buy the Escalation Map Pack: it comes with it
Call of the dead, convoy, hotel, zoo, and stockpile.
From the related link the next Zombie Map for the Call of Duty Black Ops map pack 2 Escalation will be to Survive Call of The Dead
The escalation map pack and Zombie map Call of the Dead for Call of Duty Black Ops comes out 30 days after the May 3 2011 release for the Xbox 360 on June 3 2011
