Walkthrough: Chapter 6 The Fall (Part 2)

Door Prize Achievement / Trophy

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. At the beginning of Chapter 6 you'll have to penetrate the 1960s Aperture facility. After flying through the Aperture logo you'll come to an area with a tall elevator. You must use the elevator shaft as a gravity boost to get across a chasm. On one end of this chasm is a platform with three of the Vitrified Doors. Listen to the audio that plays when you hit the buttons in front of each of the sealed doors.

Now, play through the level until you get to the 1971-era test facility. At this point, Cave will start talking about testing on hobos and you'll know you are in the right area. Below one of the test spheres and a giant Aperture logo in its 70s cooper Black Font is a room marked CONTROL ROOM in yellow lettering. You can use a portal to get high above the Control Room and enter a small office. In the corner of this office is a cabinet with a door behind it. Enter this door to find a secret hallway that leads to a dock (see Ship Overboard Achievement /Trophy). The final three Vitrified Doors can be found here.

Ship Overboard Achievement / Trophy

For Ship Overboard, play through Chapter 6: The Fall until you get to the 1971-era test facility. At this point, Cave will start talking about testing on hobos and you'll know you are in the right area. Below one of the test spheres and a giant Aperture logo in its 70s cooper Black Font is a room marked CONTROL ROOM in yellow lettering. You can use a portal to get high above the Control Room and enter a small office. In the corner of this office is a cabinet with a door behind it. Enter this door to find a secret hallway that leads to a dock. At the end of the walkway by the docks, you'll find an orange life preserver marked "BOREALIS." Examine this to get the Achievement / Trophy. This is a reference to the Aperture ship Borealis seen at the end of Half Life 2: Episode 2.

In this room a cube is trapped in a glass box, while Blue Gel streams out of a pipe in one corner. make a save when you enter the room so you can reset the puzzle if you need to. You must shoot a portal under the Gel and over the crate to coat the cube in goo. The cube will then bounce around until it breaks the glass. Eventually it will break out of the glass. To get the Schrodinger's Catch Achievement / Trophy you must catch this cube before it touches the ground. Stand between the entrance and the gel spout and just hope the cube comes flying your way. It may take a few tries!
