Is there some FOSS or Linux native Battle Royale?

Hi, bth I never played fortnite, but I tried PUBG Mobile and COD Mobile and I honestly enjoyed the Battle Royale gameplay, and I think I'm kinda good at it given the number of times I've won, but I got tired of those games needing to download a shit ton of content and trying to make me pay for shit, so I haven't played in a while.

So, I wonder if someone already made a FOSS Battle Royal, at least as an optional game mode inside some other game, like, there are plenty of quake clones and I wanted to know if there is some battle royal around.
