I actually kinda knew this was going to happen, but yesterday Jonathan Coulton and Harmonix confirmed that "Still Alive", the end song from the game Portal, (which was named Game of the Year at the Gamer's Developer Conference this past week) will be part of the downloadable content for the game sometime soon. For those of you who are not familiar with the song, you see all the different iterations right here on the YouTubes. I can't wait to play this. With JoCo no less. Whee!
ON EDIT: Check this out. Coulton, Lady V (Veronica Belmont), Merlin Mann and Leo Laporte playing "Still Alive" live in SF. A great watch!
