Are there are any FPS shooters on the genre of UT (or even Quake3) but modern, not remasters?
I've been missing a lot the frenetic gameplay of those, used to play a lot of UT at a decent level but nowadays I only see tactical FPSs or the likes of Counter-Strike/Battlefield with a high player count.
Outing myself as a parent of young kids here, but I have been genuinely surprised how good Hypershot on Roblox is. It reminds me of Unreal Tournament a lot and is really easy to play, I've been hooked for a few weeks. It cuts everything down to the basics like UT without all the bells and whistles modern AAA games have. Oh and it's totally free (but with all the monetization attempts Roblox games tend to have, though they aren't necessary to play even at a high level).
Diabotical was heavily inspired by Quakeworld/Quake3/UT arena shooter FPS.
https://www.warsow.net/ is good and runs on pretty much everything. Plays like a mix between UT and Quake3.
Tribes 3: Rivals is a load of fun. Flying around on jetpacks helps raise the skill ceiling.
Arena shooters have been relegated to side modes in other, bigger games. Probably the last big shooter with that as its focus was Halo: Infinite, but that struggled to stay relevant and its next big update will be its last.
there are but they are pretty niche, so mostly you play against bots or against friends.
This one is the last one I heard of but I also haven't followed the scene much lately: https://store.steampowered.com/app/324810/TOXIKK/
Not that I can really think of - there's the adjacent Sauerbraten, but that's a similar vintage!
Please point me to the nearest meat grinder. I'm jonesing for breakneck speed mayhem!
Shootmania was supposed to be it.
If you like 1v1/2v2 gamemodes, Straftat is pretty amazing: https://store.steampowered.com/app/2386720/STRAFTAT/
Not really unfortunately. This video goes a bit into why (https://www.youtube.com/watch?v=F-t37idOfvk), but the short version is the skill floor (or ceiling?) was too high, making it unwelcoming for people to just pick up, unlike a COD-like shooter.
Dusk is more Quakeish than UTish, but well worth a look. The graphics are deliberately low fidelity 90s retro, but the gameplay is tight.
Quake Champions?
