"Still Alive" is a song featured in the closing credits of the 2007 video game Portal. It was composed and arranged by Jonathan Coulton and was performed by Ellen McLain, who portrayed the Portal antagonist and subject of the song, GLaDOS. The song originated in a meeting between two Valve developers and Coulton about him writing a song for the company, which Coulton accepted as he was a fan of Valve's Half-Life series, to which Portal is related. The song was released on The Orange Box Soundtrack on December 21, 2007, along with an exclusive vocal mix not heard in the game.
