Dying Light 2 will be easily one of the biggest releases this year and the good news is that it works on Linux without any messing around. Note: personal purchase.
Tested with Steam Play Proton (specifically Proton Experimental), so far the experience has been pretty good, although with a caveat that I've yet to try co-op. At least as far as single-player goes, it works really well. Interestingly for a lot of players on Windows, the game just crashed trying to start the game - no such problem here on Linux.
Showing the true power of Proton as a compatibility layer, having such a high-profile release working out of the box on day-1 is a really fantastic thing for Linux. The original Dying Light is also one of my favourite open-world Zombie-smashers, so it's quite exciting to get to run through Dying Light 2 right away like this.
Both the DirectX 11 and 12 modes work, although switching from 11 (the default) to 12 did cause a hard lock-up requiring a reboot. After that though, loading back in and it continued working just fine. Performance between the two modes doesn't seem all that different either, at least on NVIDIA with the GeForce RTX 2080 Ti.
Considering how Techland supported the first game for so long, I think we can expect good things for the future of Dying Light 2. Techland have already promised 5+ years of continued support with free DLCs, various in-game events, bigger paid story DLC, new enemies, new weapons and much more.
Something to note is that the game does include Denuvo Anti-tamper, which caused a bit of a ruckus since Techland did not even mention it until right before the launch. Thankfully Denuvo has worked on Linux with Proton for some time now and doesn't appear to cause any playability issues here, although be careful if you switch between Proton versions for testing on Dying Light 2 as it may trip it up.
