I love grumpytrousers mumblers The National, so was particularly excited when I found out the band would be contributing a specially written song to Portal 2. And somewhat disappointed when Exile Vilify appeared in the form of the broadcast of a tinny radio in a hidden corner. Then I found this and listened to it eight hundred times in a row. Soon there will be excuses to listen to it many times over again, as Valve have set the challenge of making a video to go with the song. The winner will receive a prize pack, including a guitar signed by the band, and some Portal 2 merch. Videos need to be up on YouTube (tagged "PORTAL2NATIONALEXILE") by July 15th. Let's see an RPS reader win this one.
