The doors are opened by the buttons in the side rooms. You need to get a portal in both rooms to press the two buttons fast enough. Then, shoot the wall opposite of the receiver (the extended panel) followed by the scorch mark on the ground to get the pellet into the receiver. This has to happen very quickly, so it may take a few tries. The lift for the chamberlock will lower, and you can proceed to Chamber 16. | The doors are opened by the buttons in the side rooms.

Room 1 has a lot fewer portalable surfaces. Place a portal on the ceiling and the floor.

Room 2 has an additional forcefield, requiring a 6-portal combination. The pellet moves a little slower, which requires you to place the next portals by the time the pellet hits the wall the first time, or else it will disappear and you will have to start this room again. | Room 2 has an additional forcefield, requiring a 6-portal combination.

Room 3 has no portalable walls in the main room, and no staircase in the side room. Place an orange portal sideways as close to the emancipation field as possible. Place a blue portal on or below the camera, and come through to land on the side room’s ledge. Now place a blue portal on the floor below you. Take note of which direction the field is. If you jump off the ledge and into the portal, pressing the necessary direction, you can manage to come up with just enough momentum to walk through the field into the next section. Another method which is more guaranteed is to, after placing the orange portal similarly, place a blue portal on the ceiling of the side room above the low floor.

Now that you are with the pellet launcher and receiver, fling yourself over to the other side as normal. Notice the additional angled platforms, preventing the normal method. Trace a path backwards from the receiver, bouncing off the platforms as a pellet would, and you will discover that the pellet needs to be coming straight out of the wall next to the three angled platforms (on that same wall). So place a portal there, and another where the pellet hits the adjacent wall (not the angled platform), and watch it bounce its way to the receiver. Portal back over as normal. | Now that you are with the pellet launcher and receiver, fling yourself over to the other side as normal.

* In the first pellet room, if you place a portal on the scorch mark and another one just left of the camera, but close enough that the camera still falls, when the pellet flies through, it may start to bounce in odd directions, including slightly downwards.
