If your game doesn't open in Arch Linux, try closing steam completely, and launching the steam command from a terminal.


Then try to launch the game and observe the output.

If you see something like the following error, this guide might help.

First, install the librtmp library with the following command.


Try to run the game. If the problem still persists, check the installed libraries.


In my case there was only a /usr/lib/librtmp.so.0, but the game expected /usr/lib/librtmp.so.1. Creating a symlink fixed the issue for me.
