Which Black Ops Zombie Map should I buy?

I have 1500 microsoft points on my account and I want to buy another Black Ops map pack. I mainly play zombies so i'm looking for the pack that has the best zombie map. I already have the Rezurrection Pack and I love the moon map. So which should I buy - First Strike, Annihilation or Escalation (based on best zombie map)Which Black Ops Zombie Map should I buy?
The First Strike map pack and the Escalation map pack are the best. Ascension is a great map, well rounded, very different and awesome zombie map. You can't go wrong with it. Call of the Dead is, personally, my favorite zombie map because it is not an easy map to camp on, leaving tons of space to run loops and dodge attacks from the zombies. The easter egg is very long and intuitive also. Ascension's easter egg is just as fulfilling, though not as long.



So to be on the safe side, buy the first strike map pack and get Ascension. Its large and has great camping spots and great looping areas. If you like REALLY large maps, go with Call of the Dead. Either way, you're guaranteed a good time!
i like acsention the best... so first strike. this is only my opinion and you should also check out others 2!Which Black Ops Zombie Map should I buy?
First strike

It has the zombie map Ascension. Which is the best zombie map of them all. Its really easy and soooo fun.

The other zombie maps (call of the dead and shang ri la) are crap, really hard and pointless.



You wont regret getting First strike
Call of Duty: Black Ops Annihilation [Online Game Code] is better.Which Black Ops Zombie Map should I buy?
I personally like them all! But my favorite is also the first strike pack. Call of the Dead isn't that bad either. :D
