I really didn’t like Doom Eternal but I think that had a lot with me wanting more of Doom 2016.
I felt Eternal had too many arcade mechanics.
I vaguely recall a mod that added some Doom Eternal mechanics to Doom 2016 but searching online the closest thing I see is the inverse; a mod that makes Doom Eternal more like Doom 2016. I might check it out but I feel like the level design would limit what the mod can do.
Ex. Removing dashing I feel like would limit the player’s ability to unlock some secrets.
