Portal/Chamber 09



This chamber is more an exercise in ignoring extreme pessimism from GLaDOS, rather than a difficult challenge. The level begins with GLaDOS saying: "The Enrichment Centre regrets to inform you that this next test is impossible. Make no attempt to solve it."

Despite the pessimism, this chamber is easily solvable. Do not worry if you destroy a cube in the emancipation grid, as another one will simply be deployed for you. To begin with, create a portal at ground level so that you can take a cube up to the platform, using the fixed orange end of the portal there.

Once a cube is placed right in front of the orange portal, you have two options. You can either shoot a portal through the small opening (above the emancipation grid; with the radio on your second playthrough) so that you can simply walk through the orange portal with the cube to the button, or you can walk without the cube through the grid, and then create another portal somewhere on the other side of the room which will then lead to the cube; collect it and put it on the button to open the door and allow you to reach the chamberlock. Remember that if you pass through the grid, the blue portal will disappear.

"Fantastic. You remained resolute and resourceful in an atmosphere of extreme pessimism."
