The history of cod zombies

Blood of the dead

The aether gives us new special weapons like a flamethrower, death machine, ragnarok and the path of sorrows. Blood takes primis and us back to Alcatraz where our crew finds themselves trapped in the cycle of life and death. Things begin to change as Richthofen trying to break the cycle that dr Monty has sent them on. The hellhounds return and so does Brutus. Many things changed such as the Golden Gate Bridge is no longer accessible and the lab and outside portions of the map are now accessed and the wardens home is also accessible. The hells retriever and blundergat make their return and the blundergat has a new upgrade known as the magmagat. The golden spork has also returned. The shield allows you to gather the trapped souls in the prison and are required to activate certain things. The map ends with Richthofen sacrificing his blood to escape and the Richthofen from the revelations ending (I assume) returns breaking the vials and giving Nikolai the kronorium and they make their way to the pentagon.
