I am death incarnate!: Achievement STEAM of Wolfenstein 2: The New Colossus

The difficulty level 'I am death, incarnate!' is available from the beginning. Unlike previous games, you cannot earn this by just replaying the last chapter. There isn't even a traditional chapter select this time (just post-story free roam).
Select this difficulty when starting a new game and play through it without changing difficulty. This also unlocks the difficulty-related trophies for all lower difficulties.
