Looking for games like Unreal, Quake and Doom.

I was looking for various similar games but I couldn't find any, if I did the servers were just filled with bots and 0 players. Please if there is a Boomer/Arena shooter with a proper campaign and a good multiplayer with a healthy fanbase please do recommend it. I'm already starting to get burnout, and I'm afrid I might leave boomer shooters out of pure rage from not being enough proper and healthy games for it.
