The central element of the game’s story, Operation Resurrection, has the SS Paranormal Division unearthing the remains of Heinrich the First, a “dark knight” from Germany’s storied past who possessed powers that could help Germany win the war.
In true keeping with the Wolfenstein 3D style of including not only more “traditional” World War II stylings but also more fantastical elements, RTCW takes somewhat lengthy detours into the supernatural.
