Wolfstone 3D is an arcade game that made its debut in Wolfenstein 2: The New Colossus and is an easter egg and a parody of the original Wolfenstein 3D. Being in an alternate universe where the Nazis won WW2, the game features a propaganda figure, Elite Hans, as the protagonist fighting each member of the Kreisau Circle.
It remains faithful to the original Wolfenstein 3D episodic format mainting the 6 episodes that each contain 10 levels. The bosses have been reworked to look like the members of the Kreisau Cirlce.

Interstingly, the Pacman ghosts were also changed.
