What is the Story to Nazi Zombies

Well, to make it SERIOUSLY shortened, meteor crashes in shino numa. full of a substance called "115". Scientist called dr maxis uses 115 to create zombies. You know the map De Riese? One of dr Maxis' partners, Edward Richtofen, puts zombies through teleporter as experiment. No zombies come out the other end. Richtofen puts maxis's daughter, Samantha, puts her dog, fluffy into teleporter. comes out as mutated energy ball. The first hellhound. Fluffy pregnant so has more hellhound babys. Richtofen, for reasons I don't know, sets zombies on de riese and locks Samantha + Maxis in room with fluffy. Go figure. So Zombies start spreading and then you get Your Nazi zombies mini game. Crashed plane has NOTHING to do with it. By the way, this whole zombies thing could be Samantha wanting revenge on Richtofen. And when hellhounds come, little girl laughing. Samantha. when your get teddy from mysterey box, little girl laughing. Guess who? Richtofen is also a playable character. And Tank Dempsey is the only Soldier to survive Night of the undead and Verruckt. Although Tank, Richtofen, the Japanese guy and the Russian are all Killed at De Riese.
