I found about the remaster and im going through doom episode 1 right now on steam deck. I'm trying to wrap my head on what the differences are between this and the unity one previous. I mean theres obvious stuff like 1, 2, final mutliple other wads preinstalled along with a whole new one. Theres the hulshult remix soundtrack available and the id vault behind the scenes along with the reworked mod manager page.
Bear in mind i am doomy fool whos biggest achievement (oh yeah also steam acheevs) was beating all episodes of doom on Ultraviolence. So im not the kind of person who will notice the kind of changes that doom pros will find in a hearbeat.
