Скачать или смотреть Portal 2 Perpetual Testing Initiative music

This is a combination of the various themes you hear when solving puzzles in Portal 2 from the Steam workshop. Custom, user-made, puzzles. There are about 12 variations of the theme, and they're randomly selected. They're all 1 minute and 7 seconds in length. When you get near or crouch on a Hard Light Bridge, or ride inside an Excursion Funnel, the music changes and adds an extra layer, and you can hear those variations here. Additionally, the music will also change if you are bouncing off of Repulsion Gel (blue) or running on Propulsion Gel (orange), but I think those themes are contained/hidden within the music clips heard in the second half of this video I've made.

Music was written by Mike Morasky.
You can see (and if you have the game, play) the test chambers you see in this video here: http://steamcommunity.com/id/dogman15...
