You must catch the cube before it touches the ground to get the 'Schrodinger's Catch' achievement. Eventually it will break out of the glass. The cube will then bounce around until it breaks the glass. You must shoot a portal under the gel and over the crate to coat the cube in goo. Save the game when entering this room so you can retry the puzzle if you fail. In this room is a cube trapped in a glass box, with Blue Gel streaming out of a pipe in a corner. Play through Chapter 6: The Fall until you reach the 1958-28 room. Then, grab the Companion Cube that is depressing the button, and use an orange portal to get the Companion Cube to the exit without it getting disintegrated and get the 'Preservation Of Mass' achievement. Stare at the portrait, and GLadOS will comment on it, and you will get the 'Portrait Of A Lady' achievement.Īt the end of Chapter 2, Test Chamber 7, shoot a blue portal on the other side of the entrance to the exit of the area. On the other side of the portal is an office with a large portrait of Cave Johnson and Caroline. Do so to get the 'Pit Boss' achievement.Īt the beginning of Chapter 7: The Reunion, while facing the entrance to the 02 room on the catwalks between tests 1971-02, place a portal on the wall to your right, and look for another pad you can shoot a portal onto through the gate and past the stairs to the left. Stand at the edge of the pit overlooking his trap, and he will ask you to jump in the pit. Wheatly will plead with you to come back. Instead of continuing to run away on the catwalks, stay nearby. Pick it up to get the 'No Hard Feelings' achievement.Īt the beginning of Chapter 9, after Wheatley's Surprise, you will need to use a portal to get away from the platform just as Wheatley sends a bunch of arms to crush you. Use a portal to get onto the conveyor belt, then walk on it until a droid with a working laser beam appears. Play through Chapter 5: The Escape until you reach the conveyor belts carrying droids to the incinerator. Once there, carry the radio up to the wall to get the 'Final Transmission' achievement. Use the launchers to get through the portal and into the room beyond the window with radio in hand. Once you get the radio, backtrack through the level, and place a portal on the pad across from the window. In Chapter 2, Test Chamber 6, carry a radio (which shows up in a clump of garbage after you hit a button) into a window above the chamber. The final three Vitrified Doors can be found in this area. Enter this door to find a secret hallway that leads to a dock (where you get the 'Ship Overboard' achievement).

In the corner of this office is a cabinet with a door behind it. You can use a portal to get high above the Control Room and enter a small office. When Cave starts talking about testing on hobos, below one of the test spheres and a giant Aperture logo is a room marked 'CONTROL ROOM' in yellow lettering. Then, play through the level until you reach the 1971-era test facility. Listen to the audio that plays when you hit the buttons in front of each of the sealed doors. On one end of the chasm is a platform with three of the Vitrified Doors. You must use the elevator shaft as a gravity boost to get across a chasm. After flying through the Aperture logo, you will come to an area with a tall elevator. At the beginning of Chapter 6, you will have to penetrate the 1960s Aperture facility. In Chapter 6: The Fall, there are six sealed metal doors marked 'VITRIFIED' (Vitrified Doors) that have buttons in front of them that play unique audio clips of Cave speaking. Enter the new area to find four turrets singing a song. Jump over it, get the Refraction Cube, then use the laser to destroy that turret to open the grate. There is a turret inside a ventilation grate just past the elevator in Test Chamber 16. WCC Flag: Successfully complete 'High Five'.
