A little help with achievements that many players encounter issues with.

Who's the Boss

Show the pit who's the boss.

At the very beginning of chapter 9, when Wheatley attempts to kill you, you'll quickly teleport to the bridge. Walk a little forward on the bridge. Wheatley will ask you to come back, do return. When he tells you to jump down, jump. The achievement will unlock.

Mass Conservation

Break the rules in chamber 07.

We save the life of the cube companion. First, do everything you need to do. Use the cube for its purpose, ascend to the lift. On the way to the lift, to the right of the door, there’s a wall where you can place a portal. Place one there, return, descend, grab the cube, create a second portal somewhere, and save the companion's life.

Turretactile

Launch a turret into the air from the faith plate.

The easiest achievement to complete is in chamber 6, chapter 2. When you press the button to drop the cube, a lot of debris will fall, including a turret. Send it off the plate.

Final Transmission

Find a hidden signal in one of Ratman's dens.

In chamber 6, chapter 2. You need to get into the room holding the receiver. The receiver will be amongst the debris after you press the button and summon the cube. The room is located above two lonely panels. Fortunately for players, there’s a wall across from the room that you can fly through. Use faith plates and portals.

Careful Listener

Follow GLaDOS’s advice to run away.

At the very start of Escape. When GLaDOS starts persuading you to return, saying the heroine has nothing left to do, that she has completed all the chambers, and offers you to go through the last door, proceed along the blue bridge.

Full Scan

Stand in the defective turret scanner.

Chapter 5. Scanning a sample for turrets. Remove the white turret, and before inserting the fake one, stand there yourself.

Nothing Personal

Save the turret from retribution.

Chapter 5. When you see a track with broken turrets, one of the turrets will still be blinking and saying it’s “not like that.” Take it to complete the achievement.

Schrodinger's Cube

Catch the blue cube before it falls.

Easiest to accomplish in chapter 6, in the chamber where the cube is in a glass box. Launch blue gel there and try to catch it as soon as the cube comes out of the box.

Overboard

Find the lost test.

Borealis! End of chapter 6. Open area, with “aperture” written in yellow above. I think you’ll understand. Get to the highest offices. To the left of the entrance, there’s a door blocked by cabinets, but if you get closer, the door will open. Proceed forward, look around, and you’ll get the achievement.

Door Prize

Inspect all glass panels at chamber doors.

I didn’t understand why they were termed “glass,” but oh well. In chapter 6, you need to press the button on 6 doors, each marked with the yellow label VITRIFIED. With every button press, Cave Johnson will say something. Make sure he speaks; otherwise, the achievement may not unlock. You’ll encounter 3 doors regardless; just don’t forget. The other 3 are behind a door on the way to Borealis. See above for how to get there.

Portrait of a Woman

Find the hidden portrait.

Beginning of chapter 7. A chamber with a track where you need to use the orange gel and fly to the other side. After you fly over, look to the left; there’s a small room with a painting. Proceed forward through the particle door. Find a little hole on the left above where you can place a portal. Get in there and look at the painting.

Persistence

Refuse to complete the first test in chapter 8.

Enter the chamber, stand still, and do nothing. Just wait. After a while, you’ll receive the achievement.

Smash TV

Break 11 monitors in the chambers.

Chapter 8. In Wheatley’s chambers, break the monitors through which he watches. You can break them with a laser, a cube (at speed), your body (also at speed), or if you just place a turret in front of them: it will shoot at the monitor. In chamber 5, there are 2 monitors, be careful.

Three in a Boat

Find the cube companion in the cooperative chamber.

The cube companion is located in the last chamber of the 4th co-op storyline. To pass the level, at the very end you need to use the blue sphere to teleport to a little room. Before reaching the room, quickly create a sphere to go along the office. The office will remain on the right when facing the direction in which you create the sphere. Just float into the darkness, and you’ll see the cube companion coming out from behind the glass.
