I searched for ages for console commands for toggling the HUD and stuff for screenshooting when this game first came out.

Now I'm uploading a simple text file with all available console commands for Risen 3 including HUD removal and flying cam.

In order to get them to work, you'll need to download the testmode files.
These are available on the World of Players website, in the German forums, thanks to OC Burner. I have not included the files with this coz', I didn't make 'em.

I have however included the link to this file in my file. Just copypaste and download, then extract to your Risen System folder.
