In his desire to master occult powers, Adolf Hitler captures the legendary Spear of Destiny from Versailles, sending it off to Castle Nuremberg (or Castle Wolfenstein, conflicting information is given). In order to stop Hitler, B.J. Blazkowicz is sent to interfere, marking his first chronological mission in the original series (but probably not the first in his career). B.J. enters the castle only to encounter heavy resistance by Nazi personnel. He also encounters Dr. Schabbs's mutants for the first time - necessitating Schabbs's assassination in the future.
