In addition to the multiplayer maps, there is a new Black Ops 3 DLC component for Zombies players.
Der Eisendrache is part of the time-traversing Zombies experience that starts with the Black Ops 3 Awakening DLC and continues through with three more chapters coming.
The official Black Ops 3 preview of the new Zombies experience is here with Awakening: Der Eisendrache Trailer that offers a look at the cast of the Black Ops 3 zombies DLC and a look at a dragon that inhabits the castle.
In the new Der Eisendrache trailer above we see a rocket that is poised to liftoff, electic coils, amazing weapons and lots of zombies. The team includes Nikolai Belinksi, Edward Richtofen, Takeo Masaki and "Tank" Dempsey on a suicide mission.
