Shortly after, Blazkowicz is sent to Isenstadt, but upon arriving by train, his cover is already blown by an unknown informant. He also hands over the medallion to the OSA for further research. The Nazis have begun digging for crystals, led by a general named Viktor Zetta. During a meeting there, he learns that the medallion needs crystals called Nachtsonne, mined only in a city in Germany called Isenstadt, to make use of its full power.

Hijacking a plane from the Tirpitz, he escapes and returns to the OSA headquarters. Discovered and captured, he unwittingly unleashes the power of the medallion, which kills all his foes for him. In an introduction sequence, special agent William 'B.J.' Blazkowicz steals a medallion from a general on the German battleship Tirpitz. Locations include the town's sewers, a tavern, a hospital, a farm, an underground mining facility, a church, the SS headquarters, a dig site and caverns, a cannery, a radio station, a paranormal base, a general's home, a castle, an airfield and a large zeppelin. As the game progresses, happenings in Isenstadt become stranger (military patrols are replaced by supernatural creatures, etc.). The story is set in the fictional town of Isenstadt during World War II, which the Nazis have enforced martial law in order to excavate rare Nachtsonne crystals necessary to access the ' Black Sun' dimension.
