This test chamber is the tenth bonus level of the game. It is taken from Portal: The Flash Version MapPack. The challenges of this level are unlocked when the test chamber is completed once.




  • Start the chamber by going to the left alcove next to the Buttons.
  • Place a portal onto the ceiling surface.
  • Place an another portal beneath you and while falling, place the portal that you've placed o the ceiling onto the sliver of a white part of the wall above the door. You'll be launched to the Cube. (don't be worried of you take damage, you won't die!)
  • Place a portal through the square-shaped hole in the wall.
  • Jump down to the Buttons with the Cube you've just acquired and place it on one of the Buttons.
  • Place an another portal on a nearby wall and walk onto the Light Bridge.
  • Teleport onto the upper half of the floor, where you'll encounter a Electricity Field.
  • Wait for the right time (when it's turned off) and walk over it.
  • Slide to the right into a small hatch (an arrow is pointing to the right spot).
  • Portal trough a square-shaped hole in the wall across the Electricity Field.
  • Walk over the small steps/staircase that is to your left.
  • Don't fall into the Laser Field! Instead, place a portal onto the wall across the, so-called, "cube trap".
  • Place the other portal underneath the Cube.
  • Slide back to the starting spot, down the staircase, and again, place the portal that you've put under the Cube onto the walls.
  • The cube should be automatically placed onto the Button.
    • If it's not, readjust its position so it is activating the Button.
  • Place a portal on the small white panel that you'll see trough the opened alcove.
  • Grab the Cube and go trough the portal that is closer to the Button the Cube just activated.
  • Place the Cube onto the remaining Button that is not activated.
  • Proceed trough the opened door. Be careful! You'll need to jump over the Goo to proceed to the ending elevator.
  • Continue to the Chamberlock.
