This Test Chamber is the twelfth level of the game, and introduces the player to High Energy Pellets.



  • Place a portal where the High Energy Pellet is bouncing, and the other one facing the vertical door.
  • When the pellet is on the vertical door side, place the same portal as the previous next to the button.
  • Fire a portal near you and pass through.
  • Stand on the button and wait for the pellet to reach the catcher.
  • Come back on the ground level and stay in front of the door now open.
  • Quickly, enter in the dark room, take a Turret in one of the corners, come back and knock the turret you are carrying over.
  • Wait for the other turret entering in sleep mode and do the same process for this last turret.
  • Go to the Chamberlock.
