When I initially installed and ran UNI2 the Steam Deck loading screen would not go away, even though game audio was playing in the background. Inputs were also not working, aside from the Steam Menu and game close buttons, and no Proton versions seemed to work. I wanted to test the game remotely from my PC just to see if it worked at all, which it did. After that, I Iowered the resolution to either a 1080 or 1260 size. After that, I tried launching from the Steam Deck and sure enough it worked! Proton Experimental had performance issues like screen tearing but switching to 9.0-1 hasn't given me any issues.
Too large of a resolution in the game settings caused issues
In-match sprites were broken, causing the match screen to be pure white, before switching to Proton 8.0-5.
Similar issue as the Windows version, alt-tabbing out of the game while in full-screen effectively causes the game to freeze and it will not fix itself even if the window is given focus again.
Plays exactly the same as on Windows, just needed to deal with the mild annoyance of finding the right Proton version. Which might be the case once the game updates again.
Works perfectly out of the box
Used Proton 9.0-4
opening movie played, gameplay was fine, multiplayer also worked fine
Works with no tinkering required
Issue with playing opening video, which doesn't matter.
The opening video has an issue which can safely be ignored. Works fine with my fightstick (xinput).
There don't seem to be any issues that aren't also present in the Windows version of the game, and there are some issues that Windows users report that I haven't seen (lobby lockups and issues with alt+tab). Overall, it works as expected.

Used Varies different Proton builds
Won't get past the "loading game" screen the deck starts when starting the game. Have to press "b" to get out. Weirdly on the destop mode the game does kinda launch. You can get the intro to play but there will be no window. Game is playing without showing the window. Tried varies launch options to change the resolution to try to see if that would fix it but to no avail. Used to work but not anymore.
Before, I was able to run Uni2 without any issues. Now the game crashes before it reaches the menu.
It's a fantastic game, I thoroughly enjoyed the time I played it; however, the recent update makes me wonder if I'll ever get to play it again as it now crashes before getting to the menu.
Last update seemingly broke netplay on Linux, as the game now crashes whenever you connect to another player.
Intro movie has no audio since it's WMV. Supposedly you can replace it with an MP4 file with the same name for audio? Haven't tried.
As of last update, netplay on Linux is seemingly broken. 100% consistent crash to desktop when connecting to another player in any capacity. Doesn't happen on Windows.
Previous report was submitted when the PC version had online multiplayer issues. Several patches have been issued and I have observed no issues since. The game plays very well on the Deck and due to its sprite-based graphics, and the Deck's smaller display resolution, this may even be a better platform to play on than a typical PC with a larger 1440p+ monitor.
The game runs near perfectly, but having inputs drop for seamingly no reason would ruin the experience of more advance players.
Missing the intro video which isn't too important
For some reason keyboard inputs work differently. Inputs drop in places they shouldn't. Doing a [236] input will only give a [26] dropping the input.

There is a Vulkan error during the opening cutscene. However, you can bypass it if you open another window on top of game's window, and then everything works fine.
Haven't tested online yet, since it seems to be unstable at the moment. Also, game is (pseudo) forced to 720p resolution, even with fullscreen mode and higher resolutions, but that's not a Linux-specific problem.
Works perfectly, no issues.
Steam reviews mention issues with multiplayer and crashing but I was able to enter multiplayer and had no crashes so far.
Game runs seemlessly when messing around in the menus, color palette editor, mission and training modes. Seems like a slam dunk at first, but there are issues proton can't fix. Matchmaking currently doesn't work, private online lobbies sometimes crash, resolution seems locked to 720p and a few other issues make this hard to reccomend over the ps5 version at the moment. If you want to stick it out, I presume this will be a fine enough way to play the game once core issues with the implimentaiton have been fixed.
As of Jan 24, online multiplayer is broken for the PC client, so that was untestable on Steam Deck.
I think it's the game's fault, not Proton
Certain videos do not play without GE, otherwise game works fine.
Fun to play with friends. Online functionality is slightly broken and the port is unstable.
Note that these crashes also seem to occur on Windows. They appear to be issues with the port itself.
The game hangs on player match search; this also appears to be an issue with the port itself and not a Linux-specific bug.
