Question about difficulty mode

[JorgeJunior]

Hi!
What is it that makes Aesir mode a nightmare? Is it equivalent to GMGOW in God of War?

I remember that, in Darksiders 2, the Nightmare mode didn't save your progress. If you died, you had to go back to the beginning of the game.

Nothing that dramatic, your game will still be saved and you can in fact change difficulty up and down at time you want, so just try it out.

The hardest difficulty just forces all enemies to be 60 levels above your at all time, that means every enemy will be red and unless you are heavily upgraded and geared it will be wise to avoid combat and stay in stealth as much as you can.
