Looks really good, but my own vision of Doom is so different to what they've done. I liked and completed 2016 overall, but didn't like jumping parts, felt out of place. Also really don't like the melee to regain health. I own Eternal but not played yet as I know some enemies are bullets sponges you have to kill in melee. The only melee I want in Doom is the chainsaw. I don't want to regain health by doing melee moves, I want to use health packs and mostly keep distance from the monsters that would be so horrifying that it reinstates the survival horror aspect and feel of the original games.
It's controversial but I prefer Doom 1 to Doom 2016, the atmosphere and sense of being on a mission is better in the original game, it just feels more dangerous, 2016 didn't scare or immerse me like parts of the original Doom did. I went back and played the originals afterwards, the atmosphere in them is so good.
My modern take on Doom would be total back to basics with maybe 10 weapons, each designed to be the best seen in any game. Horrifying enemies that aren't bullet sponges, but you get a lot more of them at once. Actual powerful feeling weapons again that will kill anything if you shoot them enough times - no stupid gimmicks, no you must run towards enemy and do a melee to actually kill them, no healing off enemies, health packs only.
A return to some shorter levels, more secrets, alternate routes, a game designed to be speedrun and replayed a lot rather than having annoying road blocks that feel like you're suddenly playing an arena shooter for 20 minutes in the middle of story based game. Visually a lot darker, use of shadows and darkness, very few bright colours and a focus on horrifying enemies that are dumber and easier to kill than Doom 2016 but attack in great hordes. I want the fear and sense of being overrun back in the Doom games, not really annoying enemies that appear or twos or threes and take ages and stupid gimmicks to kill.
Rant over, but I really do hope we get a return to the more original style of Doom someday.
