You are B. J. Blazkowicz, a highly decorated Army Ranger recruited into the Office of Secret Actions (OSA) tasked with escaping and then returning to Castle Wolfenstein in an attempt to thwart Heinrich Himmler's occult and genetic experiments. Himmler believes himself to be a reincarnation of a 10th century dark prince, Henry the Fowler, also known as Heinrich. Through genetic engineering and the harnessing of occult powers, Himmler hopes to raise an unstoppable army to level the Allies once and for all. You must first escape from imprisonment in the castle to report the strange creatures and happenings in and around Wolfenstein to the OSA. Your mission takes a drastic turn as you learn the depth of Himmler's plans and what you must do to defeat the evil he has unleashed. This is what you have been trained for. Your surroundings will be dangerous and hostile. The OSA is currently tracking activities believed to be associated with Himmler in locations throughout Germany including villages overrun by the occult, hidden crypts, forests, air bases, secret weapons facilities, and genetic labs. There are more, and you must find them. Failure is not an option. If Himmler succeeds, the war is over for the Allies... and the war is over for everyone.
