Call of Duty: World at War just got more awesome with the confirmation of "zombie mode". To unlock, just complete the main storyline. Then you and up to 4 friends can pit your wits against horders of NAZI ZOMBIES!

More zombies?
Looks interesting.

Poor Nazis.. people are never going to stop picking on them
its my favorite mode. this is goign to be a tough choice, I want both GoW2 and CoDWaW
Is this another of those cool Halloween things that game makers are doing?
TOO MANY ZOMBIES D=
Even GTA IV has zombies now...however this looks pretty good and I'll probably get it around christmas time. My priority is LEFT 4 DEAD and FIFA 09. Not so sure about fifa...90% chance I'll get it though.
zombie mode is cool, but an endless swarm sucks. i like the idea of being able to board up windows and stuff...but it's the same reason why im not that interested in GOW2 horde mode. too repetitive with no end in sight. L4D is where it's at, imo.
GTA has zombies?! wtf? ive never seen them.

I heard it's a halloween thing and they run around in gold pants.
Wow. I have to find that!
I just saw the video. Ugh it doesnt look too much fun unless its a 16 player match.

Yeah, I wonder why people could POSSIBLY pick on Nazis 
i could shoot Nazi's alllllllll day.
