Compatibility Report

I can confirm that videos do not play (just black screens, have to wait/press keys to continue). Other than that offline single player appears to work fine (did not try online multiplayer).

#1464 Videos are: WMV, VC-1 + WMA

No, but the native Linux version is not well tested and doesn't work out of the box with certain distributions other than Ubuntu. I haven't been able to get it work under Manjaro with the circulating workarounds. But even if it works, you have no functioning Steam overlay there, too. That's the reason why I switched to Proton for the game.

I was able to play Worms on Manjaro by following this guide.

Hope this helps.

I just tried it again with the guide and recognized that I formerly haven't adjusted the path names in the script. Now the native Linux version works here, too. I also had to install the packages lib32-libcurl-gnutls and wavpack and symlink the libcurl-gnutls. So thank you very much for the tip!

By the way: Other than via Proton, video playback is working in the native Linux version thanks to wavpack. And I can use special characters like vowels there, too. Ranked multiplayer and Steam overlay are broken in both variants, though. And the game only has a 60 Hz option (other than with Proton, where I can set and use up to 144 Hz), which leads to a hardly playable mouse lag. I will switch back to Proton now.

Edit: As a workaround I let Steam switch to US keyboard layout when the game starts, so I can at least use "?" in the ingame chat. After I exit the game it switches automatically back to my German layout. This is the specific game launch option:

gamemoderun setxkbmap us && strangle 140 %command%; setxkbmap de

As you can see, it involves the Feral gamemode and the fps limiter libstrangle, too.

Any workaround to get ranked multiplayer working on Linux?

I changed the compatibility to Proton 5.13 and finally was able to open the game.

On flatpak steam works with latest community build of proton 6.3 20210506.

Videos does not play, but works.

Just tried to run Worms W.M.D (327030) with Proton:

• Proton 9.0-4
• Proton Experimental [bleeding-edge]
• Proton Experimental

with no launch options, game just exits right away, no window shows up (just the Steam button goes through PLAY→CANCEL→STOP→PLAY states).

There was nothing useful in Steam output and Proton log.
I've decided to remove ~/.local/share/Steam/steamapps/compatdata/327030 directory.
The game then started to work just fine, duh!

Not sure what was that about, sharing it just as a heads up for anyone that would have similar problem. Unfortunately I've deleted that compatdata directory for real already and can't check if there were any logs :/ It also could be an issue of Steam Cloud synchronizing files including graphical settings from Windows PC that I've used to play it in the meantime. Anyway, it works now.

One issue tho - Steam Overlay is not showing up.
Running it via gamescope fixes that, so everything is fine!

In my experience, deleting compatdata has been necessary for all games when switching Proton versions
