Walkthrough
  1. 1
    Return to the larger room. Drop your sphere and look at the left slanted piece of wall.
  2. 2
    Shoot a portal at the ceiling above the left slanted piece. It should bounce off and hit the receptacle.
  3. 3
    Grab the sphere again and enter the only room you haven't gone into yet.
  4. 4
    Before entering too far, turn around and fire a portal (the one that was on the slanted portion) at the wall on the far side of the room so that an energy ball traveling through it will enter the door into your current room.
  5. 5
    Grab the sphere and go over to the right button. Put it on.
  6. 6
    Wait for the sphere to shoot out of the portal and enter the first door (the one you just opened by putting the sphere on the button).
  7. 7
    Once it is inside of the first door, quickly take the sphere off of the button.
  8. 8
    Run behind the door (near the receptacle) with the sphere and place it on the button on the opposite side. The sphere will hit the button.
  9. 9
    Return into the larger room. Shoot a portal to the walkway area above your current location (the ones on the same level as the pistons) and walk through the portal on the ground level with you (make sure you bring the sphere with you).
  10. 10
    Jump along all of the pistons and jump off to the left on the final one. Go up the stairs.
  11. 11
    In here, put down the sphere (don't drop it down the pit) and turn around. Place one portal near the middle of the wall and the other in the pit.
  12. 12
    Grab the sphere and jump off of the ledge. While in the air, use the push button to project the sphere through the hole. Be sure to fall into the portal to be propelled to the other side of the barrier.
  13. 13
    Shoot a portal at the wall on the ledge near you, then shoot a portal at the ground. Bring the sphere along with you through the portal.
  14. 14
    Run down the hall and place the sphere on the button. Run into the newly-opened small room and press the button.
  15. 15
    Run back to the sphere and grab it. Drop it into the fire. Turn around and run into the chamberlock.

Advanced Test Chamber 18 (AC18)

  1. Run out of the chamberlock and on to the small piece of ground on top of the water. Turn and face the door you just came from. Look up and shoot a portal as far above the door as you can. Shoot the other at your feet.
  2. While falling, try to fall through the portal you just shot. Then, as you are flying through the air, look to your right. When you see a large white wall and a white floor above it (you can barely see it) shoot a portal at the ground above the wall.
  3. When you land, look towards the large white wall and shoot a portal at it where you can jump into it. Jump through. You should end up above the wall you just shot a portal at. Look at the four large pistons. Near the bottom of them, and to the right, you can see a small object. Shoot a portal there.
  4. Now carefully walk through the portal on the ground near you. As you are falling through, move your analog stick backwards to prevent yourself from falling into the water. Look at the pistons. If you look through diagonally you can see a small white portion of wall near the far left piston. Shoot a portal there (being careful that the portal near you doesn't push you into the water while the other is changing places) and re-enter the portal near you.
  5. Now look up and to the right. You should see a white portion of wall above two pistons. Shoot a portal there and re-enter the portal near you.
  6. Run over to the ledge to see the platform you were previously on. Shoot a portal at it and jump down through to be propelled onto a platform with a button. Go through the door and into the small room.
  7. Push the button, and then crouch under the piston as it moves out. Be sure to exit to the left of the piston, or you will be shot and probably killed.
  8. Look at the wall to the left to find an indention in the wall (where an energy ball would be shot, if there were any energy balls here). Shoot a portal at the wall 1 tile down and 3 tiles to the right. Shoot the other at the wall near you.
  9. Don't go all the way through portal but stand on the threshold. Look to the left and down a little bit to find a very small sliver of white wall. Shoot the portal that is near the "energy ball" spot at it, and as it's traveling, step backwards out of the portal, or risk falling into the water.
  10. Go through the portal again. Push the button, and shoot a portal at the piece of far wall that comes out. Look downward from the ledge you are on. Shoot a portal near the left part and jump down and through. As you are flying out of the other portal, be sure you are heading into the portal you just jumped into. If you aren't, re-shoot your portal so you will end up going through it. You will also get shot a few times while doing this, but don't worry. If you do it right, you won't die.
  11. You should end up on a high platform. Run to the far back of the platform to get out of the way of the turrets. When they reset, run to the back left corner and shoot a portal to the far right of the far platform (the wall too the far right of the door we came out of to get in here). Grab the box, and run off of the ledge. Try to aim yourself and the box through the portal.
  12. Place the box near the doorway, then return near your portal. Re-place the portal where you put it the first time (1 tile down and 3 tiles to the right of the energy ball mark), then go through the portal near you. Shoot the portal that is near the "energy ball" spot at the small white sliver and run backwards out of the portal before it pushes you into the water. Re-enter the portal.
  13. Press the button, and go back through the portal near you. Grab the box and run through the newly-opened doorway. Crouch under the piston.
