This test chamber is the thirteenth 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.



  • By using the portal gun, place one of the portals on the X mark that's above the Turret and the other portal onto the walls or the flood that is portalable (has to be within your reach).
  • Fall onto the Sentry Turret by going through the portals and knock it down.
  • Get back on the floor, avoiding the turret that is behind the Light Bridge's bullets.
  • Shoot a portal trough the Light Bridge and go inside the room where the cube dispenser is.
  • Grab the previously dropped Cube.
  • Leave the room and portal over to the higher ledge where the X was.
  • Stand on the Piston platform while holding the cube and block the shot bullets of the Turret with the cube that you are holding.
  • Go to the Pedestal Button and press it. The button will activate an Energy Pellet dispenser that will knock down the turret.
  • Using the cube, redirect the Energy Pellet into the catcher.
  • After you have redirected the pellet to the catcher, while crouching, crawl into the small hole what was used to transport the pellet to you (with the cube).
  • Drop down into the pit and place the cube onto the Button.
  • Drop down even deeper and quickly avoid the Turret.
  • Kill the turret.
  • With portals, go back and grab the cube from the button and place it on the other button seen in the same room with Goo.
  • In the way, over the goo, by the corner, portal onto the sinking platform and bring the cube with you.
  • Wait for the right time and jump onto the platform.
  • Drop the cube and portal onto a ledge.
  • Grab the cube back and quickly jump trough the portal previously placed.
  • Drop the cube and crouch behind it. This will keep you safe from the Turret.
  • Place a portal behind the turret and, avoiding the turret's bullets, knock it down.
  • Peek over and portal onto the other sinking platform (with the cube).
  • Quickly jump onto the ledge and knock the turret down.
  • Peek over and portal onto the other sinking platform (with the cube).
  • Quickly jump onto the ledge.
  • Wait for the Unstationary Scaffold to arrive.
  • Jump onto the platform.
  • While riding the Scaffold, use the cube as a shield against the turret's fire.
  • Optional: Portal over to the turrets and knock them down.
  • Put the portal that will help you reach the upper ledge (do not go into them yet!).
  • Press the Pedestal Button.
  • Quickly place a portal trough the door before it closes.
  • Proceed to the Chamberlock/Elevator to finish the chamber.
