Portal 2 Achievements/Trophies Guide

Portrait of a Lady
In the beginning of Chapter 7: The Reunion, on the catwalks between tests 1971-01 and 1971-02, facing the entrance to the 02 room, create a portal on the wall to your right and look for another pad you can shoot your portal through the game and past the stairs to the left. You will find an office on the other side of the portal with a large Portrait of Cave Johnson and Caroline. Stare on the Portrait to earn this achievement/Trophy.

Overclocker
You need to solve Test Chamber 10 in Chapter 2 in under 70 seconds to earn this achievement. Read through our Portal 2 Walkthrough to know how-to do that.

Door Prize
Penetrate the 1960s Aperture facility at the beginning of the chapter and fly through the aperture logo to reach an area with a large elevator.

Use the elevator shaft as a gravity boost to get across to the platform. On one end of this platform are three of these Vitrified Doors. Listen to the audio by pressing the buttons in front of these doors.

Play through the level until you get to the area where Cave starts talking about testing on hobos. Below these test spheres and a giant Aperture logo is a room marked Control Room in yellow.

Use the portal to get above the Control Room and enter a small office. Find a cabinet in the corner of this offer that has a door behind it. Enter the door and you will find a secret passage leading to a dock. You will find the remaining Vitrified doors here and earn the achievement.

Ship Overboard

At the end of passage, you will find an orange life preserver marked “BOREALIS.” Examine it get this achievemnt/trophy. It’s a reference to the Aperture ship Borealis seen at the end of Half Life 2: Episode 2.

Schrodinger’s Catch
Play through Chapter 6: The Fall till you reach the 1958 28th room. Enter the room and you will notice a cube trapped in a glass box, while blue gel streams out of the pipe in one corner of the room. Save your progress here as it can get tricky.

Now, you must shoot a portal under the gel and over the crate to get the cube in motion. It will then be able to break the glass with its momentum. When it does, you need to catch this cube before it touches the ground. Trick is to stand between the entrance and gel hoping the cube comes flying your way.

Final Transmission
