Linux Gaming

I play a lot of Apex Legends. It works very well on Linux.

Shatterline and Caliber

Both free to play, on Steam, and work using Proton.

Hunt Showdown runs on Linux with Proton and it has EAC

CS:GO, Halo MCC, Overwatch 2

though I don't know if OW2 counts as good anymore, certainly not a fan of the changes, but it still works on Linux

Insurgency Sandstorm is pretty good and CS:GO is always a classic go-to.

Older game but red orchestra 2 is a classic ww2 shooter with a decent online community. Matches are around the 20 - 30 minute mark.

Splitgate

Bzflag

Jk

I play apex legends and sometimes overwatch. Csgo is also an option but i haven't played it yet

Xonotic is always a good one.

My go-tos are tf2 and tf2 - that is Team Fortress 2 and Titanfall 2. Both work great on Linux and have really dedicated communities. Titanfall 2 even has the Northstar client.

I like Xonotic

Battlefield 4 is still good. Plays well under Linux, graphics are good, servers are still packed and it's quite challenging.

Krunker is nice for a quick match. You can play it directly from your browser or download it from steam

Why not just CS:GO? But I’m only saying this because I have no real recommendation tbh. For offline I can recommend Ravenfield. It’s really fun even though the native Linux version is kind of broken when using mods which is kinda the point of the game. Works fine using Proton though
