In short, because this is a Wolfenstein game, it's a first-person shooter with a supernatural twist. The story begins where Return to Castle Wolfenstein left off, and you can expect the usual hokey nonsense. B.J. discovers a mysterious amulet with special powers and hands it over to his superiors. Turns out the amulet contains crystals which only originate from one place on Earth - the fictional German town of Eisenstat. B.J. is dispatched to find out just what those naughty Nazis are up to, and wouldn't you know it, they're attempting to access a supernatural energy source known as the Black Sun. Probably not as a means to charge their laptops more efficiently.
