This is the thirtieth level of the game, and is the first level to be set within a fully-repaired and functional Aperture Science Test Chamber. This level requires the player to combine precise Portal-placement and multiple Thermal Discouragement Beams in order to proceed.

Hazards

Walkthrough

  • Walk over to the Beams and place a portal on the wall on the left-side where the Beam ends.
  • Place the other portal to the column facing the three Receptacles.
  • Pick up the cube that is already redirecting one of the Beams. Place the cube in front of the portal, so the Beam activates the middle Receptacle.
  • Pick up the other cube and place it over the beam coming from the ceiling. Aim it at the Receptacle on the right side.
  • Go to the Chamberlock.

It is also possible to complete this chamber without placing any portals. This is a more difficult solution to the puzzle so the basic solution is recomended
