It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

entux: Anyone else having this issue. Not a single error message. It just refuses to start for me and dmesg spits out the following:

ptrace attach of "./TidesOfNumenera"[1436] was attempted by "/usr/bin/gdb -ex attach 1436 --ex info threads --ex thread apply all bt --batch"[1477]

Hello entux,

Please contact our support at and provide your system info, but by generating a GOG system report. It can be done by using a script that you will find in your copy of game.

That way we can identify more accurately what can be the cause of the issue.
entux: The game NEEDS SDL_AUDIODRIVER=pulse!!! If you set that it will start. Albeit without sound. If you want sound as well you need to have pulseaudio installed. Unity3d is shit on a stick.

(this is a c/p from my other thread)
Ah, yes. Most, if not all modern games require PulseAudio to work. I am glad that you found a way to resolve your problem :) I am marking your post as a solution!
