With Wolfenstein: The Old Blood, US action hero B.J. Blazkowicz finds himself back in Nazi territory, exploring new areas of Castle Wolfenstein and the quaint village nearby. Some of these areas are, in fact, B.J.'s nightmares, which look an awful lot like Wolfenstein 3D. In fact, playing through all nine of them means playing through all of the classic corridor shooter.
There's a nightmare in each chapter, and each one nets you an Achievement/Trophy upon completion, plus there's the bonus Die, Grösse, die! award for completing them all. This guide will show you where to find all nine nightmares, starting on page two.
