This unnamed Co-op Test Shaft featured in the cooperative campaign of Portal 2 is one of the nine Enrichment Shafts from the salt mines owned by Aperture Science Innovators, found underneath the computer-aided Enrichment Center.

This test shaft had originally ran through cooperative testing during the vintage era, but was later utilized by GLaDOS after she gains more sight of the facility with previous help of ATLAS and P-body. It is featured within Test Course 5: Mobility Gels.

Overview Edit

  • Like Test Shaft 09, this shaft was designed to test Mobility Gels but with two test subjects testing together, but only the Repulsion and Propulsion Gels. However according to GLaDOS this did not work, as humans "treat their friends as enemies", hence attempting to complete these tests with ATLAS and P-body.
  • Given the presence of the Propulsion Gel, the shaft was built sometime in the 70s and was later tempered and adjusted to the modern Aperture testing elements by GLaDOS.
  • The shaft is connected to the Hub through elevators, and to the Extended Relaxation Annex through a gargantuan hatch. As seen in Test Shaft 09, it is also connected to the other Enrichment Shafts through an underground train network.
  • While Chell had only ventured throughout Test Shaft 09, ATLAS and P-body were sent possibly further through the salt mines under orders from GLaDOS to recover stored human Test Subjects in the Extended Relaxation Annex.

Layout Edit

The shaft is made of 11 Enrichment Spheres.

Enrichment Sphere 01 Edit

The first test involves the use of the Repulsion Gel to jump on Unstationary Scaffolds.

Enrichment Sphere 02 Edit

Includes an Excursion Funnel combined with the Repulsion Gel in order to reach a distant platform.

Enrichment Sphere 03 Edit

Contains two test chambers, both including a Hard Light Bridge as a surface for placing the Gel.

Enrichment Sphere 04 Edit

Introduced the two-walls technique to jump on with the Gel, eventually a Hard Light Bridge being later the second wall.

Enrichment Sphere 05 Edit

This is the first sphere where the use of the Repulsion Gel is alternated to the Propulsion Gel to catch cubes, also in combination with Crushers.

Enrichment Sphere 06 Edit

Involves also Turrets and a Weighted Pivot Cube and contains an Emancipation Grill as a testing element.

Enrichment Sphere 07 Edit

This second to last sphere includes time restriction to pick up the cube through the Propulsion Gel.

Enrichment Sphere 08 Edit

The final sphere mixes the previous testing elements to approach to the Human Vault, but cuts off the Hard Light Bridge.

Enrichment Sphere 09 Edit

This sphere is empty and out of ATLAS and P-body's reach.

Enrichment Sphere 10 Edit

This sphere is empty and out of ATLAS and P-body's reach

Enrichment Sphere 11 Edit

This sphere is empty and out of ATLAS and P-body's reach

Behind the scenes Edit

  • The Enrichment Shafts are what remains of the game F-STOP, which originally was to be a prequel to Portal set during Cave Johnson's era, hence the old-fashioned design of the areas. It was not to feature portals, and Johnson was to be a protagonist later turning antagonist, a role adapted for Wheatley in the final game.[1]

Trivia Edit

  • The shaft appears to start from the top, while the others from the bottom, but it simply could have been reworked by GLaDOS to make ATLAS and P-body enter the Vault.
