I do not own any part of any of these trailers by valve or the song. I am only making it to express the love for this song as well as the Portal 2 series and how well the two mix. The real surprise I found while making this is how they hardly needed any editing, and fit parts of the music with the action very well. Anyways, enjoy and buy portal 2, it's a classic, amazing game! Many more videos like this to come.
