A long time ago where games were still installed with DVD’s, there was a special video, which was shown during SCII Wings of Liberty installation.
This is available on many YouTube channels. Like this one:
I’ve searched for the German version of this video for a long time, but so far no luck. Since the game already had German audio at that time, I’d assume it should be there somewhere in Blizz archives.
Or maybe someone has it …
I’d really love to have that video
