In doing so I discovered there are some interesting options for players who want a brutal challenge.
The whole game is also sped up to 150% of normal speed - which makes things slightly frantic.
All this is done through a set of options that makes difficulty much more tweakable than in previous games.

It’s possible these might get changed before release, but take a gander anyway.
Increasing the game’s speed is enough by itself to make my nose bleed.
I’ll stick to a regular preset, thanks.

And yes, this simply un-Dooms Doom.
But it was enough to prove that for accessibility purposes alone it might be useful to some.
