This is the twenty-second level of the game, and is set within a dilapidated Test Chamber. This level reintroduces the player to Turrets, and the way in which they can be disabled through direct interaction, or by using a Weighted Storage Cube.

  • Pick up the Turret in front of you and throw it sideways to disable it.
  • Look around the corner and fire a portal on the wall behind the second turret. Then place the other portal on the wall next to you.
  • Lift the turret through the portal and disable it by putting it sideways on the floor.
  • Go to the corner where the turret was and go to the right.
  • Place a portal under the third turret and it will fall through and be disabled.
  • Go where the third turret used to be and then go up the stairs.
  • Shoot a portal above the nearest turret and the other one under the Weighted Storage Cube on the floor in front of you.
  • Do the same to the other turret.
  • Pick up the last Storage Cube and carry it to the other side of the glass.
  • Go around the corner and use the Storage Cube as a shield when knocking over the remaining three turrets from closest to the furthest.
    • This section can also be passed by placing portals above the final three turrets, and a portal on a wall in safety, and dropping cubes on the turrets.
  • When all of the turrets are disabled, place the Storage Cube on the button.
  • Go in the Chamberlock and jump down from the catwalk.
  • Walk to the catwalk on the left and through the door.
