Sometime after GLaDOS' takeover and shortly after the Combine invasion of Earth, Chell is awakened in her Relaxation Vault, and guided as a Test Subject by GLaDOS, utilizing the completed Aperture Science Handheld Portal Device. However, she effectively loses this race when the Black Mesa Incident occurs mere days later. GLaDOS aims to beat Black Mesa in the race for portal technology. GLaDOS still manages to wrestle control of the facility from her now trapped creators, however, and is soon in full control of the Enrichment Center, with several Test Subjects as her rats, including Aperture employee Doug Rattmann. Quickly, the Aperture employees fit her with a Morality Core to ensure that she is kept under control. Within one picosecond of being active, GLaDOS becomes self-aware, locks down the entire facility, hoping to seize control, and floods the Enrichment Center with a deadly neurotoxin. GLaDOS is fully completed on May 200-, and is switched on during the Aperture Science's annual bring-your-daughter-to-work-day. During that time, the Aperture Science Red Phone plan is implemented in case GLaDOS appears to become sentient and godlike, requiring an employee to sit by a red phone on a desk in GLaDOS chamber's entrance hall. In 1996, the Disk Operating System parts of GLaDOS are completed, and work begins on the Genetic Lifeform component. To counter this, construction of the first Genetic Lifeform and Disk Operating System ( GLaDOS) begins in Aperture Laboratories, with the aims to accelerate the 'Portal' project and to develop the first Artificial Intelligence.

In 1986, Aperture Science heard of similar portal technology being developed by Black Mesa.

Testing for the 'Portal' project calls for the construction of the Enrichment Center, a large area of the Aperture Laboratories Underground consisting of Test Chambers and offices, where Test Subjects test the ASHPD. He then laid out a three-tier plan for the future of his company: the Heimlich Counter-Maneuver, the Take-A-Wish Foundation, and most notably, the 'Portal' project, which gives birth to the development of the Aperture Science Handheld Portal Device. It is unknown if the same complex is used during the time Aperture was a shower curtain manufacturer.Īfter contracting moon rock poisoning in 1974, both of Aperture CEO Cave Johnson's kidneys failed in 1976.

Built in Michigan, USA sometime after the founding of Aperture Science in 1947 when Aperture's products were branded "Aperture Science Innovators".
