The Unseen History of Portal (VNN Exclusive)

E-Mail : tylermcvicker@ Steam Group : Patreon : Today on Valve News Network, we go over the entire history of Portal, and talk about many things that were left in Beta or cut entirely. Most of what is seen in this video has never been seen before by the public, and I am very happy to be able to share it with you today. I would like to thank everyone that has helped me make this video, as it took quite a long time
