"Still Alive" is the closing song from Valve's 2007 puzzle game Portal, sung by the villainous AI GlaDOS after players think they have destroyed her. Written by musician Jonathan Coulton and voiced by Ellen McLain, the credits track turned into a runaway fan favorite that spawned hundreds of YouTube covers and cemented itself as one of gaming's defining end themes.

Overview

"Still Alive" plays over the credits of Portal after players believe they have destroyed GlaDOS, the passive-aggressive AI antagonist, only for her to break into song and reveal the title's twist1. Composer Jonathan Coulton wrote the piece from GlaDOS's perspective, framing the whole game as a workplace grievance letter set to an upbeat synth-pop track, with lines about the test subject being a "huge success" undercut by threats and dark jokes about the incinerated Weighted Companion Cube2.

Ellen McLain, who voices GlaDOS throughout the game, performs the vocals through the same filtered, robotic effect used for the character's dialogue3. That in-character delivery is a big part of why the song took on a life of its own outside the game: it works as a self-contained villain monologue, so fans stripped it out of Portal and treated it like a standalone pop single3. Covers range from straight piano arrangements to children's choirs, ocarina performances and 8-bit chiptune remakes3.

Date

2007

Portal shipped on October 9, 2007 as part of Valve's Orange Box bundle for Windows and Xbox 3603. Valve commissioned Jonathan Coulton, an independent musician known for geeky web-native songs, to write an original credits track, and he composed "Still Alive" specifically for the ending sequence2. McLain reprised her GlaDOS voice for the recording, so the credits play as if the AI is quietly gloating over the player.

Once players finished the game and heard the twist, clips of the song spread quickly onto YouTube. One of the earliest known fan uploads came from YouTuber "pudgenet" on October 20, 2007, only eleven days after Portal's release4. Coulton also performed his own acoustic version live and uploaded it to YouTube on November 16, 2007, giving the song a second life as a Coulton concert staple5.

How It Spread

In the weeks after Portal's release, "Still Alive" spread on YouTube through fan covers on piano, strings, ocarina, children's choir and other instruments3. A piano arrangement uploaded on October 22, 2007 was one of the first widely shared instrumental takes6, and Coulton's own live acoustic rendition uploaded in November 2007 became a reference point for later covers5.

The song also crossed into other games and platforms. Valve packaged it as a downloadable track for the Rock Band series, and community charts for Guitar Hero followed3. YTMND, then a hub for looping-image gags, hosted several Portal pages built around the track, including GlaDOS-themed and NES chiptune versions3. Video edits kept the McLain vocal but swapped the visuals for typography, Garry's Mod machinima, World of Warcraft footage and Newgrounds animations3.

The track's fanbase carried over when Valve released Portal 2 in 2011 with a new Coulton-written credits song, "Want You Gone", and "Still Alive" is still the reference point people cite when the sequel's ending is discussed. Slowed-down and remix uploads keep appearing on services like SoundCloud years later7.

How to Use This Meme

The song itself is not a template so much as a reference: quoting the GlaDOS twist ending ("This was a triumph", "I'm making a note here: huge success") became shorthand online for celebrating a hollow or ironic win. Fans typically cover the song on an unusual instrument, dub it over unrelated game footage, or splice it into other Valve properties as a callback to the Portal ending3.
