an original song by The National is part of Portal 2
, the first-person puzzle game sequel due for release next month. "The inclusion of the original song, Still Alive, in the first Portal game was part of what made the game special," said Chet Faliszek, writer at Valve. "For Portal 2, we wanted to extend the use of music. When Bug Music mentioned to us that The National might be interested, we jumped at the opportunity to work with them."
