- — Description
Nazi Zombies is a game mode that is featured in Call of Duty: WWII, developed by Sledgehammer Games. It is based in an alternate reality where Dr. Straub has created an undead army in a final effort to change the outcome of World War 2.
In this iteration of Nazi Zombies, the point system has been changed to use “jolts” in an effort to “rationalize wall-buys and abilities.” Perks have been replaced with augmentations that are obtained by shocking a hand in various machines. Matchmaking now features a Casual and Hardcore setting, where Casual guides players through a simpler Easter Egg and Hardcore leaves the players to figure out a much tougher one without hints. The first available map is “The Final Reich”, which takes place in a town called Mittelberg and allows players to traverse through the town and Dr. Straub’s bunker.
Austrian engineer Marie Fischer is sent on a mission to her hometown village of Mittelburg, Bavaria by her commanding officer, Major Hank Rideau, to retrieve lost artifacts stolen by the Nazis for experimentation, as well as rescue her brother, Klaus Fischer, who provided the information. Klaus has been unwillingly working with their lead scientist Dr. Peter Straub and weapons expert Colonel Heinz Richter on a project to exploit a mystical energy dubbed "Geistkraft" to turn the tide of the war in the Nazis favor. Marie is assisted on her mission by a group of MFAA operatives including Scottish ex-art thief Drostan Hynd, Art Historian-turned-French Resistance fighter Olivia Durant and United States Army captain Jefferson Potts, all of whom have significant knowledge on the stolen arts and relics. However, on their train ride to Mittelburg, the group is attacked by an unknown colossal being. Marie is stranded from the others, and finds herself taking temporary refuge at a small farmhouse nearby, where she holds out against hordes of dead German soldiers reanimated by the Geistkraft energy, until she is able to make her way to the village.
After reuniting with the other three, Marie and the group proceed further down into the village's hidden bunker, where Straub has set up his laboratory. There, they then discover the horrific experiments that Dr. Straub and colonel Richter conducted. The group continues fending off against Straub's undead horde, as well as Richter, whose obsession on the weaponization of the Geistkraft energy puts him at odds with Straub. Eventually, the group recovers the artifact, the hilt of Emperor Frederick Barbarossa's Sword. They then encounter the creature from earlier, a humanoid-shaped amalgam of numerous body parts sewn and stitched together, dubbed the Panzermörder, with Klaus fused into the creature's chest. Using special magnetized batteries, the group manages to stun the Panzermörder and attach the batteries onto it, causing it to be attracted to Richter's zeppelin flying above the village. The Zeppelin explodes, killing the Panzermörder and freeing Klaus from its body. The hilt's power somehow revives Klaus, causing him to be possessed by an unknown entity. Klaus staggers into the village, and tells Marie and the others to continue fighting, and that the emperor must never return, before activating a fire trap, seemingly killing himself.
Days later, the crew receives intel on Dr. Straub's current whereabouts, leading them to the remote Heligoland islands where Straub has been continuing his experiments with the Geistkraft energy. The group continues their pursuit of Dr. Straub and the next piece of the emperor's sword, but comes into struggle with the Nazi forces and Straub's latest undead monstrosities protecting island as he prepares for an assault on Britain. While on the island, Drostan shares with the group details of his employment by Heinrich Himmler to search for an artifact on this island, and how he narrowly escaped death at the Nazi's hands while also recovering several ancient scrolls. Upon solving several riddles and puzzles, the group finds a ritual chamber dedicated to the goddess Nerthus, where they require the pommel of the sword. The group then calls in an airstrike to destroy the facility on the island as they escape on one of Dr. Straub's Zeppelins as he and his forces return to Berlin in response to Adolf Hitler's call for rescue .
