This Test Chamber is the fifth level of the game, and requires the player to use their knowledge of Flinging techniques.


  • None


  • Across the corridor, avoiding the block.
  • Look down to the end of the pit. Shoot the first portal on the floor, just under the ledge at the other side of the room, and place the other on the extended ceiling panel.
  • Jump through the portal on the floor. Then, before touching the ground, put the last portal you placed previously -the one on the ceiling- under you.
  • With the momentum you gained, you should be able to reach the ledge.
  • Proceed to the Chamberlock after the door.
