Ambiance - Old Aperture Ambiance

Located approximately 4500m underground in a vast disused salt mine in Upper Michigan, little is known about Aperture other than it was abandoned and sealed in the 1980s. It is now in a serious state of collapse and access is strictly prohibited because of the dangers of falling debris and increased radiation levels detected near the surface. A small research team was recently allowed exclusive access for 2 hours to the 4.5km deep control room. One researcher reported hearing the continuous echo of distant falling debris and they were astonished to find working electrical equipment and could breathe unaided. A giant ventilation duct was still in operation but they were unable to trace the power source in the limited time they had. Further plans to investigate the facility have since been planned due to radiation levels being lower than expected. A single photograph and an audio recording have been leaked to the public.

To this day, nobody really knows what happened down there.

Seriously though, It's just some old aperture ambiance recorded from Portal 2. Relax and enjoy.
