ooc surveillance footage

Vacuum pipes cropped up occasionally in the original Portal, but this time we wanted to show that this was the main way that Aperture transported all of its supplies about the facility. It felt very true to Aperture, in that it seemed like an inefficient and ridiculously expensive solution to their transport problems. We also wanted it to feel more violent and physical than before, with objects constantly ricocheting against the sides of the pipes. It was as if Aperture had no real control over the system, and no real care for the things they were transporting. After all, they have thousands of the things.
