User blog:PotatOS/Nazi Zombies Ideas

Well, we all know Nazi Zombies. One of the best sub-games ever created. Well, know, I would like to know what improvements they should do / what should they add. That includes, but is not limited to: Well, you get what I mean. Jot down your Ideas here, and lets make this a BIG BIG blog. So, goodnight :D
 * Bad-Ass weaponary (AKA Wunderwaffe, Monkey Bomb. Similar things)
 * Map Layouts (Big, AKA Der Riese, or small, AKA Dome in WaW Multiplayer)
 * New Perk-a-Cola (e.g. Marathon. Would save lots of lives in my case...)
 * Location (Again in WaW, Vietnam, heck, maybe even Prypiat...)
 * New Features (e.g. Traits of the characters)
 * New back-story
 * Intelligent Zombies (Maybe some hide. Maybe, very rarely, they can use a gun...)
