"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 voiced 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, which is set in the same universe as Portal. The song was released on The Orange Box Soundtrack on December 21, 2007, along with an exclusive vocal mix not heard in the game.
The song is displayed on what appears to be a computer console, playing after GLaDOS is defeated by protagonist Chell, with the lyrics revealing that GLaDOS is, in fact, "still alive." The song received praise for its humor and the quality of its performance. It has been featured in multiple venues, including at the 2009 Press Start -Symphony of Games-, a yearly Japanese concert event to showcase the musical works of video games. It was also featured as a free downloadable song for the Rock Band series, originally released on April 1, 2008. A rerecorded version, with Sara Quin on lead vocals, appears on Coulton's 2011 album Artificial Heart.
The song "Still Alive" was written by Jonathan Coulton and performed by Ellen McLain for the 2007 video game Portal. McLain also provides the voice for GLaDOS in this song, an artificial intelligence and the game's antagonist. "Still Alive" is sung from the perspective of GLaDOS, used as the song that runs over the game's credits. By the end of the game, Chell, the game's protagonist who has been misled and placed in life-threatening situations within the game's testing facility setting by GLaDOS, eventually defeated her. However, the song disputes this, with GLaDOS exclaiming that she was still alive and that things were a success. She also exclaims that she is still testing, and references the Combine invasion of Earth in the Half-Life series.
