Just played this again last night, on my PS3 however. I love the Nazi Zombie Mode, one of the best Horde-esque Modes out there. Just wish that, for once, I could get a team of four together... I've never got more than two people in the same game.
Yes, it was actually meant to be called: 'She doesn't numa numa' but the translation didn't go very well
I have it on my ps3 too! Thank god Xbox 360s aren't completely taking over... My username's Bobwooly.
Apparently it didn't do so well because the makers went back to the old war style like on the originals.
