YouTube user SkipPrime has created a simply amazing Half-Life 2 video entitled Half-Life 2: Godspeed You! Gordon Freeman. The video takes lyrics from the song "The Dead Flag Blues" by Godspeed You! Black Emperor and shows how closely the song relates to the events in HL2. I don't want to spoil anything in the video, but if you're a Half-Life fan it's absolutely worth the watch.
