The Cold Boot
Back to Portal 2
Place a portal on the wall to the right of the exit door and one on the floor next to you. Drop through to land on a platform by the door. GLaDOS will release a laser. Place a portal at the bottom of the laser and on the roof above the laser receptor. This will raise the platform so you can get to the exit.
Jump over the laser, place a portal on the floor and one under the cube in the next room. Grab the cube and use it to deflect the laser onto the receptor. Walk up the steps, place a portal on the floor and the second under the cube. Grab the cube and place it on the button to open the exit.
In the next room wait for GLaDOS to prepare the puzzle by lifting up a platform in the middle. Portal up to the ledge, grab the cube and jump across to the middle platform. Deflect the laser into the receptor. Use two portals to deflect the second laser into the second receptor in the roof above the ledge. Head through the door to the next area.
Place a portal on the wall to the left and the other on the platform opposite with the red button. Press the button and a cube will drop down. Place the second portal on the wall opposite the laser. If you have the first portal placed correctly the laser will go through the portal and hit the receptor. This starts the platform moving. Hop onto the platform, use the cube to block the laser as you go back the other way. Hop off on the other side, place the cube on the button and go through the door.
Use the bouncer to bounce across to the other side and push the red button. A cube will bounce up and down in the middle. Bounce across just as the cube is bouncing up and grab it in the air. Bounce back to the door, place the cube on the button and go through.
This room features a series of bouncers with two sloped panels to the right. Place a portal on the sloped panel you can see and hop on the bouncer. As you’re flung towards the two panels place the second portal on the panel in front of you. You’ll get flung towards the exit. Press the red button and junk will come hurling towards you. Press it again for a cube. Place a portal on the roof above the red button and one on the wall. Drop the cube through the portal so it lands on the red button and opens the door.
Grab the companion cube and use it to block the laser. Stand on the lift and put a portal under the cube so that it moves out of the way. The laser will hit the receptor and the lift will go back up with you on it.
Place a portal on one of the sloped panels up the top and the other under the cube so you can grab the cube. Place a portal on the right sloped panel and one at the bottom of the hole. Grab the cube and drop down through the portal to get flung across to the other side. Place the cube on the button to lift up a platform.
Use the other sloped panel to fling yourself to the platform and head out the exit.
Go through the barrier and press the red button. A cube will drop down. You need to get the cube to the other side of the barrier without passing through it. Go through the barrier and place a portal on the wall and the other on the wall in the room beyond the barrier by using the small round window. Take the cube through the barrier and use it to deflect the laser onto the receptor. Go through the door to end this section.
