Aside from the Installationfiles for Linux not working, because a few libraries for that game seem to be missing. I did find the following Entry in the file output.log (file is in the game subdirectory):

Analytics.Google [INFO] User-Agent: Mozilla/5.0 (Linux; Linux 4_16 Arch rolling 64bit; English) Unity/4.6.2f1 (Standalone)

A short look in the Logs - also output.log - for the other Shadowrun games (Linux) did reveal the same lines.

I would like to know how and why the above line does get into the file output.log.

bump

I am too concerned.

The games use Unity3d, which does telemetry by default. Since I run all games in a network namespace with only the loopback device (and prior to that, always unplugged my network before playing games), I don't know what most users do to defeat it. I suggest using google.
