It was released on May 5 2015 for PC, Xbox One and Playstation 4. The prequel is set in 1946 and contains two missions called "The Dark Secrets of Helga Von Schabbs" and "Rudi Jäger and the Den of Wolves". The location of the game is Castle Wolfenstein in the German Alps. New weapons include the pipe, the bolt rifle and a handy grenade launcher. "Wolfenstein: The Old Blood" contains occult and supernatural elements, as well as many references to the older titles. Despite this, the so called "supernatural" elements are heavily implied to have a mundane scientific explanation.
