Editing for the last few hours I've come to understand that Nazi Zombies was not nearly as popular as I had originally thought, it kinda makes me sad. I mean, Gears of War's Horde mode is pretty popular, why isn't Nazi Zombies. Most of it I think has to do with the fact that it is incredibly difficult. The other part is the fact that you are destined for failure no matter how hard you try. No matter how many Zombies you leave in your wake of destruction two more pop up to replace it ever single time. It's an overwhelming feeling I think. Still, it pains me to see something with so much potential fall by the wayside. Maybe Treyarch will realize it had something special and use it in the next game, maybe not. We'll see I guess.

I like Nazi Zombies but I am not a big fan of any of the Horde mode genres but as a whole Nazi Zombies was as good as any of them to me.

See, I guess that's just me. I liked Nazi Zombies more than any other Horde-type game. The perks, characters, I guess just the idea of it pulls my interest more than Gears.

1. CoD:WaW - Nazi Zombies
2. Uncharted 2:AT - Survival
3. Gears of War 2 - Horde

I was a big fan of it as well. In fact Nazi Zombies was the only reason me and my brother bought the map packs.

It wasn't popular enough because instead of being on the disc from day 1, it was gay ass DLC instead. And the zombies that came with the game sucked compared to the 1st and 3rd map pack. Hopefully the next one will have more zombies on day 1

I friggin' loved it, I can't even tell you how many hours I spent playing it. Except for Verruckt. I hated that map. 
 
1 - Shi No Numa 
2 - Der Riese 
3 - Nacht der Untoten 
4 - Verruckt

It was alright. I was never a huge WaW player because I spent more time in CoD4. But the Zombies mode was certainly one reason I played WaW.

@nail1080:  Nazi Zombies came on day one, you just had to beat the campaign to play it.

Well, it's been a while since I posted this and YES NAZI ZOMBIES IS BACK!
