You Can't. It's only available in World At War and Black Ops.
It not a part of Call of Duty Modern Warfare 2
no
No Zombie mode is not part of the Spec Ops and is a different game developer
you cannot unlock zombie mode in modern warfare. Zombie mode is only avalible in black ops.
Zombies are not part of MW2
No, Modern Warfare 2 has Special Ops missions instead.
No only spec ops.
There is no Zombie mode for Modern Warfare 2. It is a Treyarch exclusive and not used by Infinity Ward. In Zombie mode you kill all the zombies and they come back again on a new level and again with more power on the next level endlessly until you die. You can not win ever. In Modern Warfare 2 The Mode is not called Zombies infact it's a more like horde on Gears of War 2 you have to kill many waves of enemies,
No they do not have Zombie Mode a Map where you have only Zombies. Those are for World at War and Black OPs apparently yes but you kill zombie dogs and different zombies not nazi zombies
No, Don't think it because it's in modern Time. Maybe downloadable as a mod, but not in the game I think. There will be a zombie mode. Just not Nazi zombies. There will also be zombie dogs. Zombie mode is an exclusive of Treyarch who develops the World At War and Black Ops Call of Duty games and not part of the game development of Infinity Ward who do the call of duty modem warfare series games
It is unknown at this time if any zombie game mode will be included in-game. Infinity Ward is developing MW2, while Treyarch designed CoD:WaW. It's a possibility, but highly unlikely.
It was only a rumor and MW2 does not contain a Alien Terrorist mode, an alien mode, or an alien zombie mode. They were not part of the two map packs for the game or Part of the Game design for Nintendo Modern Warfare Reflex or Modern Warfare Mobilized editions or any other Call of Duty series released up to and including MW3.
