I'm almost done with the final episode of Wolfenstein 3D, and I'm mostly having fun... but my god, Floor 7 was the most drawn out, painful level so far. It's all tight corridors, filled with enemies who can seriously f**k you up if they get the drop on you. It somehow managed to be worse than the constant hidey holes in Floor 1, or the endless confusing swastikas shaped rooms and corridors in some of the others.
