This Test Chamber is the tenth level of the game, and introduces the player to the Infinite Jump, a highly advanced Flinging technique.



  • Place the portals on the markers.
  • Jump through the lower portal. Just after passing through, move in the air to go through the same portal. You will gain more momentum. Repeat this if necessary.
  • When you are high enough, shoot a portal on the floor behind the glass, then go back in the room entrance.
  • Fire the other portal on the lower marker, then jump through at the good time to avoid the Electricity Field.
  • Across the Electricity Field quickly and jump over the little gap.
  • Go to the Chamberlock.
