Never played it back in the day, but picked it up yesterday since you guys have been talking it up so much.
So far it's pretty solid, and they did a good job with the controls and graphics on the PS4 Pro version at least. I will say though that it doesn't feel like a Doom game, really. It feels like an experience game mod team wanted to make a Duke Nukem 3D expansion but got turned down, and were then tasked with making a Doom game, which they weren't familiar with, so they just winged it.
The power ups are in the weirdest places, nowhere near any of the action. I can't tell if certain things like Berserk are active or if they expired, so half the time I never really even benefit from the power ups since they're not adjacent to scenarios where I could use them. (though in some areas it seems they realized they needed to drop certain things like health packs and ammo in specific spots because otherwise you can't pass that area)
The enemy designs are pretty mixed too. Some of the soldiers look neat, but the Imp and the Pinky look hilariously awful. Just TERRIBLE. I'm only 4 levels in so I haven't encountered all of them, but I did see a bunch in the opening startup screen. I think some of the weapon design changes are a little weird, but for the most part things feel and play pretty well. Thankfully I'm not getting any input lag like I STILL GET with Doom 1/2.
