User blog comment:Damac1214/Vonderhaar tweets interesting tweet about the possible future of Zombies/@comment-3967954-20130530120344/@comment-3967954-20130530183943

None of the Black Ops maps that the zombies team worked on revolutionised zombies like MotD did, they were all fairly similar in terms of features. Previously, a few new weapons and traps would have been fine, but I think they're going to need to add more if they want to keep people interested since MotD showcased loads of new stuff - including an easter egg that actually ends the game, like so many people have been asking for - and the zombies team has, so far, struggled to do anything on-par with that.
