Complete Portal Part 7 by navigating Test Chamber 05, solving puzzles involving buttons, boxes, and portals to progress through the Aperture Science facility.

In this section, we'll cover the technical aspects of portal creation and then guide you through Test Chamber 05. Initially, dynamic collision generation for portals took up to 500 milliseconds, a noticeable delay. This was improved to 10 milliseconds by creating temporary physics environments in bubbles around portals, an imperceptible pause.

Walkthrough
  1. 1
    Shoot a portal and take the box through it. Place the box on the button to open the door.
  2. 2
    The computer announces that the next chamber will not be monitored. Head through the chamberlock and into the elevator.
  3. 3
    You will enter Test Chamber 05 (TC05). Approach the panel to activate it. The only hazard is dropping a box on your head. Turn right.
  4. 4
    Look up above the doorway to find and shoot the 'Camera Shy' turret.
  5. 5
    Head through the door to find two buttons, two platforms, and a pit.
  6. 6
    A commentary node will appear as you walk through the door, near the far right platform.
  7. 7
    Shoot a portal and go through it to reach a piston. You will see a box on the other side.
  8. 8
    Shoot a portal across the gap toward the box.
  9. 9
    Go back through your orange portal and grab the box.
  10. 10
    Jump off the platform and place the box on a button.
  11. 11
    Jump down into the pit and shoot a portal. Pick up the box and take it through the portal.
  12. 12
    From here, there are two solutions:
    • Harder Solution: Place one box on a button and stand on the other. Shoot a portal through the door, then stack the boxes next to the platform with the orange portal. Jump onto the platform and go through the orange portal.
  13. 13
    Easier Solution: Jump down with the box and place it on the other button. Go through the door.
  14. 14
    After completing the chamber, the computer reveals the previous statement about not monitoring was false. You seem trapped. Shoot a portal anywhere and go through it.
  15. 15
    Search the walls slightly above your head for a camera and shoot it.
  16. 16
    Find the chamberlock and go into the elevator.
  17. 17
    You will enter Test Chamber 06 (TC06). Run forward and look at the panel. The symbols indicate energy balls and their receptacles. Energy ball receptacles are not hazards.
  18. 18
    The computer warns about the High Energy Pellet's potential to cause permanent disabilities such as vaporization.
Tips
  • Remember to shoot any cameras you see to avoid being targeted.
  • The 'Harder Solution' involves more complex portal placement and movement, useful if you want a challenge or are stuck.
