After reading the whole article...
The lab itself WAS a WWII lab; though I don't think they specified it was an old Nazis lab. After all, the US might have been up to super-soldier stuff too.
But they say it's been occupied by modern-day (or slightly future) scientists. They've reactivated it and started doing experiments.
So, maybe the real weirdness is the current scientists' fault. Maybe they were building off the work the place was originally used for. Maybe it's something completely different. I don't think it was that specific.
It sounds interesting, but I miss Shodan. That voice was awesome. I'd love a voice synth that sounded like that, with the random stuttering. I'd use it to make ALL of my system sounds.
The concept drawings have German writing on the walls, so I'd guess it would be German.
Y'know, if it's set in the near future, they could shove in an insane machine running the place (possible more likely a hive mind type thing)... the first look inidcates the design is somewhat a fusion between biological, rotting WW2 and shiney near-future tech.
