Aperture Labratories

Aperture Science (also known as Aperture Labratories [sic]) was a research facility which developed weapons systems and teleportation technology in direct competition with the Black Mesa Research Facility.

The Enrichment Centre was an Aperture Science facility which was used to test Aperture’s technologies and personnel. Although it was claimed that learning and enjoyment were the main purposes of the centre, test participants were often put through dangerous tests involving many hazardous materials and obstacles. The facility was, at the end of its life-span, unmanned and run by the GLaDOS AI, whose core was destroyed by test participant #234, Chell. The facility is believed to be no-longer operational.
