Shadows of Evil
Looks to include standard parts of Zombies like power-ups and perk-a-cola machines, but also has a new aesthetic of a city nightlife as opposed to the decayed ruins we're used to. New characters and Zombie types (which don't much resemble the Zombies but what can you do?) as well as a new perk machine doing various abilities.
Damn, despite how familiar it looks Zombies still seems like a breath of fresh air compared to the teasers for the Campaign and Multiplayer so far.
