The main objective is to use the momentum of the Faith Plates to put a Weighted Storage Cube on a button on a ledge.īefore the Weighted Storage Cube can be received through the Vital Apparatus Vent, several items from Portal, from later areas or from the co-op campaign drop out, including a chair, a Defective Turret, two Edgeless Safety Cubes, a working radio, a water bottle, and a CD or disc. This test involves more advanced use of Aerial Faith Plates. GLaDOS claims that they were invented to see "how well Test Subjects could solve problems whilst being catapulted into space." The results showed "they could not." (Ironically, the scenario was actually the reason for the Excursion Funnel being invented.) After the test, GLaDOS states that Chell's air supply is actually "freshened" carbon dioxide. Introduces the Aerial Faith Plate testing element. They are fixed to the wall and can only travel up and down or left and right along the same wall. It is similar to the Unstationary Scaffold, but the rail platform is much more limited.

Wheatley can also be briefly seen after the platform in the center raises up on a rail that runs under the floor. A Ratmann den can be found in this test chamber, along with an Aperture Science Radio that plays " Exile Vilify". In third chamber, Chell uses a Weighted Pivot Cube and portals to redirect beams to receptacles to open the chamberlock door. Wheatley can be seen briefly near a torn room where the Redirection Cube can be obtained. It involves redirecting lasers via the Cube and using portals. In this test, GLaDOS introduces the Discouragement Redirection Cubes that were built just before Chell had tried to escape in Portal. The player uses the beam to activate a lift which sends them up to the doorway. It is actually Test Chamber 06 of GLaDOS' original testing track, but with the Thermal Discouragement Beam replacing the energy pellet. Starting the second chapter, The Cold Boot, it is the first chamber GLaDOS sends Chell through after her. Chell will witness the drastic changes of these chambers from being overgrown and ruined, to a more clean and perfected state. Since her awakening, GLaDOS has been fixing not only the chambers related to the test course, but the entire Enrichment Center itself. This testing course was used after GLaDOS had been reactivated by accident, courtesy of Wheatley. The final chamber for this course would have been Test Chamber 22, which is a death trap for Chell. Its start, the very last test chamber from the original testing track in Portal, is connected to the Incinerator Room. GLaDOS' Testing Track (Portal 2) is the newly built testing course featured in Portal 2, consisting of 22 test chambers.
