Locations/Test Chambers

The Enrichment Center #751 contains numerous Test Chambers where test subjects are trained to perform simple to complicated tasks using the Aperture Science Handheld Portal Device. The tests are monitored by GLaDOS and security cameras. Aperture Science personnel can watch the tests in small offices (observation rooms) spread around the Test Chambers.

The Test Chambers' atmosphere is notable. The walls and floors are plain gray (altough they change to yellowish gray in Portal 2), and the feeling is as if you are in a clinic or clean room. In BTS areas, the atmosphere becomes dark and foreboding while Chell navigates through the innards of the Enrichment Center.

The original Portal's Test Chambers range from 00 to 19 (a total of 20 chambers). In Portal:AAA, there will be 50 chambers. Portal 2 has several sets of chambers: before activating GLaDOS there's 10 chambers, GLaDOS makes 22 chambers and in Cave Johnson's and Wheatley's areas there's still more test chambers.
