I'm playing this f2p shit battle roayle with gacha and waifus called Farlight 84 and somehow I'm liking it.
I hate battle roayles, but I can't find any other good shooters that work well on Linux. I tried Strinova, but I realised that I dislike CS like games more than battle royales.
The F84 has solid mechanics, the battleroayle is not so irritating because your teammates can respawn you and the weapons don't have tiers of totally bullshit vs OP, so even without any attachments, if you land a solid hit on someone you're golden. The gacha stuff is just cosmetics and some of that shit is available to purchase without the gacha part. The characters are good, they are not OP and their abilities are not something that you use them more than shooting (my problem with Marvel Rivals is that I realised that I spent more time doing everything except shooting). The bad part of the game is that if you are not playing ranked or you are playing when the server population is low the match is mostly bots.
Honestly half the reason I'm digging the game is that the chinese water dragon girl and the catgirl hacker are both characters that fit really well the way I like to play.
