If Doom played like Doom 3 - DARK n SLOW - How atmosphere can change a game!

If Brutal Doom was played like Doom 3's style. Using UDV "Ultimate Doom Visor" Hud mod addon , it has multiple Features. Including making the lighting "Dark" on multiple levels. I set it to darker. And toggled off "run only". So I moving at walking speeds. Also using a spooky sound track to set the scary mood. Feels like a totally different game. I will try with the "pitch black" setting next. Also using maps of chaos. Doom 2016 Doom 4
