Test Chambers

Test Chambers are a vital part of the Portal series. Thanks to the Security Cameras fixed onto the walls of Test Chambers at various points, GLaDOS can track a Test Subject's movements and progress. There are multiple Test Chambers throughout The Enrichment Centre. However, in Portal 2 they are instantly created by GLaDOS and Wheatley (using robotic arms carrying panels and combining them with other panels to form a ceiling, floor, and walls of a chamber) as one progresses through the tests. This new method of creation allows for an almost infinite amount of test chamber combinations within the Enrichment Centre. Upon entering a Test Chamber one acquires a bare (minimal) feeling, similar to a hospital with its sterile environment; this is due to the lighting used within chambers, and the colors of the panels as well.
