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.

Bonus Chambers

In addition to the standard test chambers exist two forms of bonus test chambers; only test chambers 13 through 18 have bonus versions. Bonus chambers only exist within Portal, and can be accessed from the main menu.

Challenge Chambers

These chambers are identical to the standard versions, however they introduce an additional layer of goal-based puzzles. These include completing the map with the:

• Least amount of steps taken
• Least amount of Portals deployed
• Least time elapsed

Advanced Chambers

These are variants of the test chambers which have been redesigned with an advanced difficulty curve, for instance by decreasing the number of portalable surfaces, or by increasing the presence of hazard water.
