Wolfenstein: The Old Blood

With last year’s Wolfenstein: The New Order, developer MachineGames established how they could pay good homage to the 1992 id Software original—hiding the game’s first level as an Easter Egg. Well, those Easter Eggs are back. There are nine Nightmare levels in The Old Blood, one for each chapter in the game (Prologue + 8 Chapters). They cover the entirety of Episode One of Wolfenstein 3D, including the boss fight against Hans Grösse and the secret level (Floor 10).

Much like the standard sets of collectibles in the game—letters and gold items—nearly all of nightmare levels (which are triggered by finding a particular bed and interacting with it) will be tucked away in well-hidden rooms or along forgotten passageways that are not always directly taken when pursuing the main objective of your mission. As such, be sure to explore each and every Chapter carefully and refer to your map when necessary if you desire to uncover any black spots that might be hiding collectibles. Additionally, while using the map, take note that collectibles will be marked with a glowing question mark if you haves unlocked the "Eagle Eye" perk. On top of this, the perk also makes collectibles visible on your HUD by indicating their location with a clear white circle if you are close by (much like how objectives are marked on the HUD by clear blue circles).

The nightmares may prove to be a tad overwhelming given each level’s maze-like design, but with enough persistence and exploration, coupled with the use of the in-game map, completing the levels shouldn’t be too hard. If you happen to die while playing the nightmares, you’ll have to retry the whole level from the beginning but the map will remain uncovered. As a general note on how to complete these missions, you'll want to explore the level, find a silver key, and then find a locked metal door. After using the aforementioned key on such a door, you'll eventually find an elevator which will be the level's "exit." This achievement will unlock once all nine nightmare levels in the game have been completed.
