re: Which Call of Duty has the best Zombie mode?

Ascension on BO is great. Lock down the the hover room by the PHD flopper. Die Rise on BO2 is pretty fun. Use the spring to kill all the jumper things to get a free perk and 2000 points every few rounds and hold down the roof under the ramp. Make sure you get the AN ASAP. You can last all game with it if you get enough max ammos. Remember always have jugernaught or you won't sand a chance past level 8 or so.
