Portal 2 Walkthrough → Chapter 7: Reunion
We're heading off to a new challenge. Climb the elevated area and activate the console. Quickly create portals under the orange gel flow and on the surface facing the ramp. The orange gel accelerates our movement. If we run forward, we won't be able to fly over, so we'll have to run backwards. Once on the other side, create a portal on the surface to the left and another on the elevated area with the console.
Repeat this process, flooding the new area with liquid. Fly over, collect the cube, and return. Place the cube on the button and fly across the new ramp. The arrows point upward, to the console. Create a portal under it, walk toward the ramp, and now accelerate not toward the ramp, but toward the surface, where we're also creating a portal. Thanks to our momentum, we reach the console and activate it.
In the next test, we'll cover the path with orange gel again. There's also a patch of surface on the ceiling just before the chasm. Create a portal on it and cover a small area of the floor with blue gel. This will act as a springboard. Accelerate and fly over. Create an even higher portal to fly to the exit. Create a portal on the area we used to cover the path. To reach it, you'll have to accelerate backwards and press the jump button at the right time, and also aim for the portal accurately.
So, in this next test, we'll do everything step by step. First, you need to get the cube. On the opposite side, you'll see arrows on the floor and two surfaces. Create portals on the half-bent surface and under the blue gel. Then create portals on the surface perpendicular to the floor and under the orange gel.
Now, having gained speed, we can easily fly to the cube. We take it to the red button, but before placing the cube on it, fill the surface of the platform with blue gel. It will flip over when the cube is placed on the button. The exit is at the top right, and the ramp is at the top left. Create portals on the wall in front of the ramp and under the blue gel. Transfer the portal from under the gel to the surface where the path was poured. Accelerate along the orange path and fly to the exit.
We reach the new workshop and activate three levers. Now we can use three gels. The white gel allows us to create portals on any surface. We descend and see an iron bridge above, and white gel even higher. We create a portal on it and jump down, jumping off the flowing blue gel to reach the other side. Before racing along the orange path, we create a portal on the wall marked with a special sign.
We emerge onto the surface and create a portal on the right side of the slightly bent surface. Now we return to the path and fly straight ahead through the previously created portals. In one of the rooms, we find a button that opens the door. In the first test with the white gel, we need to spray the following: the ramp, the wall of one of the tall towers, and the floor where we'll be jumping to create momentum.
Having reached the elevator shaft, we begin climbing toward the elevator itself using portals. The elevator has no ceiling, so we create a portal on the floor. We exit the elevator and turn left. We create a portal and jump down. We fly through the elevator ceiling and, at the peak moment, quickly look back. We see a slightly bent surface on which we create a portal. To continue completing the challenges, we need to climb even higher. At the top, we see a slightly bent surface above the door. We must fly out through this, creating a portal.
Next, we leave the portal above the door and create another one under the blue gel. We repeat the jump again. Now we create a portal on the floor and jump to the very bottom, quickly creating a portal almost before landing. Having flown through the first portal, we create a new portal on the floor of the elevated area. For the next challenge, we create a portal above the slightly bent surface and under the white gel. We cover the path in front of the surface with orange gel.
Create a new portal on the half-bent surface, this time under the blue gel. Leave the portal on the half-bent surface and create a new portal by accelerating along the path just as you jump. There's white gel flowing on the other side, but you can climb up it. Create a portal under the white gel and where you crossed from. After exiting through the portal, you'll need to quickly create another portal on the small wall just as you jump. Once you're in the space with numerous pipes, you'll be able to reach it.
We look up and notice a metal walkway. Once there, there will be a place from which we can jump, creating a portal on the floor. We'll fly out through the wall to the booth, which is located in the corner. Therefore, we create a portal on the wall opposite the booth. If you can't reach it, try jumping properly, gaining speed, and create a portal on the wall as high as possible. In the booth, carefully look at the poster and activate the console. When the huge hatch opens, jump down and go to the lowered platform. We're off to new challenges.
