This is the first advanced Test Chamber of the game. This version is unlocked when the original Test Chamber 05 has been completed. It has the extra challenge of including a Goo entrance, less white surfaces, a harder timed puzzle and a Material Emancipation Grill near the exit.

Hazards

Walkthrough

  • Put a portal in the next room and the other near you, then jump over the Goo to pass through the portal.
  • Look up then place a portal on the highest white wallpanel, and the other on a wall near you.
  • Before going through the portal, aim the top of the pillar. Just after passing through the portal, shoot a portal on this top.
  • Go through a portal on the ground level to reach the pillar's top.
  • Fire a portal on the angled panel, and place the other at the bottom, then go through this last. You should reach the ledge after the Goo area.
  • Place the same portal as the previous on a white surface at the next level, then jump through the portal on the angled panel.
  • Go through the Material Emancipation Grill and prepare yourself for the timed puzzle. When you are ready, push the Switch and come back quickly to the vertical door now open.
  • Put a portal on the angled panel above and the other on the top of the pillar, then jump through.
  • You are now on the next level. Place a portal on the floor next to the angled panel and jump through the portal on the pillar's top.
  • With the momentum you gained, you should reach the exit. If you fail the landing, try the timed puzzle again.
  • Go to the Chamberlock.
