Doom Eternal - Hell on Earth (No Damage, Nightmare)

I'd say Hell on Earth is the most difficult level in terms of not taking any damage, you don't have your arsenal and dash, and worst thing is that most of the demons are imps and soldiers because without dash sometimes it's just unreal to dodge their attacks and you take damage.
I didn't choose the "Ultra Nightmare" difficulty, because it is nearly impossible to complete the whole game with No Damage Taken without using any checkpoints for multiple attempts.
There is so much things which can go wrong. In later levels 90% of failure is caused by random fodder demon projectiles, especially such fodder demon as soldiers and mecha-zombies, they are the most dangerous and sometimes even are number one priority to kill because of their random spread to some their attacks which makes it impossible to dodge resulting taking damage and loading last checkpoint.
Doom Eternal AI is dynamic and enemies can almost always surprise you even if you know where each one is located.
