The weighted companion ball will assist you throughout the test.
In the advanced chamber, the weighted companion cube has become a ball, the platform activations are tougher, and an extra step has been added towards the end.


*The first catcher isn't much different, since you still poolshark the pellet off the angled wall. (The glass barrier isn't much of an obstruction.)
You may quickly find that the ball seems to have a mind of its own, in that even if you set it down in a stationary setting, it may roll around aimlessly anyway. Do your best to climb the stairs as before, and then rebound the pellets as you move through the halls.
*The second catcher has both buttons raised a bit higher. You need to knock down and stand on a camera to hold both buttons down.
- Or you can push down the first door button with the companion ball, and quickly let go of the button as it passes.
Let it ping back and forth between the doors while you run behind the second door.
Open that one with the companion ball.
*The side catcher requires you to bounce the pellet above a glass barrier.


== Challenges ==
The first receiver has a glass barrier preventing the normal method of placing a portal on the angled platform. It is easy enough, however, to place one on the ceiling above the angled platform, and the pellet will bounce off and into the receiver.

=== Portals===
The second receiver has a glass barrier as well, making it more difficult to bounce the pellet in. Just use trial and error, bouncing it at different angles with the ball, and you’ll get there. Try not to get hit in the process.
 
The third receiver has both buttons in the back, at a higher level. Hold the ball onto the first door’s button, wait for the pellet to pass, then lift the ball off so that the pellet is bouncing in between the doors. Quickly move the ball to the other button before the pellet disappears, and it will bounce into the receiver.


A 2 portal solution involves:
Alternately, if you knock down a camera, you can place the ball on one button, and hop onto the camera, giving you enough height to hop to the other button yourself.


* Place gold portal at the end of the first corridor.
As you cross the platforms, you’ll notice the normal exit to the right is no longer there. Proceed to the left instead, and you’ll find an accuracy fling test. You can’t just fling from the top, as that will shoot you out too high. Instead place the portal on the seam between the top two panel layers. Drop the ball through first to make sure it’s accurate, and then fly through yourself. A simple portal on the wall to get up, and it’s off to the exit as normal.


* Place blue portal on protruding wall facing double door.
== Challenges ==
=== Portals===


Use the cube to bounce the pellet in the side room into its receiver.
Bronze at 4 portals:



Place the cube onto the button for the second door, and stand on the edge of the button for the first door, allowing the pellet to pass by without hitting you.  It will be captured by the receiver, but the emitter will continue to produce more pellets.
Proceed with the cube to the three-platform area.
# Blue portal on the second pellet’s scorch mark.
# Orange portal on the angled platform to direct the pellet into the receiver.
# Blue portal on the first pellet’s scorch mark.
# Orange portal on the extended ground level panel. Activate the other two platforms as normal, walk through the orange portal with the cube, and proceed all the way to the exit.


In front of the protruding wall, place the cube on the floor such that it will ricochet the pellet off the ceiling and into the last receiver.
Silver at 3 portals:
# Blue portal on the first pellet’s scorch mark. Proceed with the cube to the three-platform area.
# Orange portal on the angled platform to direct the pellet into the receiver. Notice that this deactivates the second pellet, and thus there is still a pellet entering the existing blue portal (see sidebar in this chamber’s walkthrough).
# Orange portal on the extended ground level panel. Activate the other two platforms as normal, walk through the orange portal with the cube, and proceed all the way to the exit.


You can now use the already placed portals to get back up top and proceed to the exit.
Gold at 2 portals:

<br>Solution 1:
# Blue portal on the first pellet’s scorch mark. Proceed with the cube to the three-platform area.
# Orange portal on the extended ground level panel. Activate the second and third receivers as normal. In this situation, the angled platform receiver is trickiest. Place or hold the cube such that the pellet will bounce off the edge of it, and hopefully rebound into the receiver eventually. This will be a bit of trial and error. Then walk through the orange portal with the cube, and proceed all the way to the exit.


Solution 2:


---Alternate 2 Portal Solution---

This solution utilizes a glitch that is difficult, but reasonable to perform under normal circumstances with the game as is. Navigate with the companion cube and enter the room where the three lifts are in the floor. Take the cube past the lifts, and place it as close to the exit hallway on the right as possible. Jump on top of the cube, and then while pressing forward (towards the exit hallway), but looking partially down, proceed to jump and grab (E) alternatively until you get onto the raised section. Note that it is possible to get up there with the cube (and thus being able to solve the chamber with 0 portals), but it is very difficult, partially due to an invisible force that pushes the cube back away from the exit hallway (in order to prevent players making themselves stuck). Once on the raised section, proceed to the area with the button.
Navigate with companion cube and enter room where the three Lifts are in the floor. Take cube to last lift and place in left corner if looking at exit direction. Jump on top of Cube and then proceed to Jump and Grab(E) alternatively till you get onto raised section(May take some practice) !*Possible if done right to get onto raised section with cube and complete level with 0 portals*!. Once on raised section proceed to area with button. Place portal on ground next to button and return for your cube. PLace opposite portal anywhere in Lift room and finish with 2 portals but not playing with pellets.
# Blue portal on the ground next to button. Return to your cube.
Awards are given at 4, 3, and 2 portals.
# Orange portal anywhere in lift room. Proceed as normal.
