In a post-credits scene, AEGIS has enough power left to initiate one final fail-safe: waking up the test subject Chell by draining the reserve power so she can escape. At the top of the elevator, she finds the town where she entered Aperture in ruins. Mel surrenders her portal gun and exits the facility in an elevator, bidding Virgil goodbye. Mel enters the code to shut down AEGIS, but while doing so, she and Virgil learn that it was flooding the facility in an attempt to destroy GLaDOS's remains.

Going through overgrown test chambers, they eventually arrive at AEGIS's central core and successfully disable it. Virgil realises the only way for Mel to escape is to disable AEGIS. With GLaDOS absent, AEGIS attempts to track them through the facility to eliminate them, deeming them potential threats to Aperture's (long-dead) scientists. Ĭontinuing upwards, they learn that the reserve power has caused a prototype security system, AEGIS, to become active. Virgil guides Mel through the remnants of the old facility, explaining that the destruction of GLaDOS, the main overseer of Aperture's facility, caused most of the control systems in the facility to falter. The voice reveals that he is not actually Cave Johnson but a maintenance core named Virgil, who offers to help Mel escape. The test goes wrong, and Mel is put in indefinite stasis.Īwakening in the distant future, Mel follows what seems to be the voice of Cave Johnson and obtains a portal gun. Aperture's CEO, Cave Johnson, speaks to Mel through pre-recorded messages via intercom, informing her that she will take part in a test of the Aperture Innovators Short Term Relaxation Vault.

In 1952, when Aperture Science is still a fledgling company, Mel, a German olympian who has been recruited as a test subject, arrives by tram at the Aperture Science Innovators headquarters in Michigan, and makes her way through Aperture's company town and into a massive underground complex. Portal Stories: Mel is set in the dilapidated underground complex of Aperture Science.
