I saw the news about a Linux version of Into the Breach, got excited and bought it today. Unfortunately, I've not had any luck running it on Arch. I get this error:

I'm using an AMD card and I do have the drivers installed.

I understand that the game officially only supports Ubuntu, but I still want to know if anyone else experienced this issue.

Same issue on Manjaro. Deleting the file works for me. Thank you.

Worked for me, too, thanks! Now I can enjoy the game.

I wonder how people figure these things out. I would've never thought of deleting that specific library.

It looks like this was fixed in v1.2.22. They also fixed an issue where the game would save into your home directory if you didn't have XDG_DATA_HOME set. It's nice to see a well-supported native Linux port!

On the other hand they created a dependency on PulseAudio with the new version. The previous version could use Alsa. For anyone else that has no sound and does not want to use Poettering's second abomination I recommend apulse.
