Walkthrough
  1. 1
    Run into the chamberlock.
  2. 2
    Run forward towards the panel in Test Chamber 16 (TC16).
  3. 3
    Turn left and walk through the door, but do not walk too far or you will be shot by turrets.
  4. 4
    While standing in the doorway, a Commentary Node will be floating near the middle of the room.
  5. 5
    Hug the doorway to the right and point at the ground of the turret. Shoot a portal there and then another portal elsewhere to cause the turret to deactivate.

    Go into the hallway. Do not go into the next room, or you will be shot at.
  7. 7
    While standing in the hallway, look into the next room and up a little for the Camera Shy achievement.

    Hug the right wall and go out until you can look through the doorway and see a wall. Shoot a portal.
  9. 9
    Shoot the other portal at the ground right in front of the doorway you are standing in. Go through.
  10. 10
    Back up until you are near the doorway and aim down the hall. If you are close enough to the door, you can see a corner along with some turret legs. Shoot a portal back against that wall, then go through the other portal near you.
  11. 11
    On the other side, press use to pick up the turret and then lift it high in the air. Drop it.

    Walk over to the corner across from the portal you just came out of. Look towards the stairs and shoot a portal as far left as you can go on the wall up the stairs.
  13. 13
    Go through the portal near you again to be behind yet another turret. Pick it up and drop it.
  14. 14
    While standing behind the turret, turn and face the wall that was behind the turret. Look up for the Camera Shy achievement.
