Complete Portal Part 12 walkthrough, including Test Chamber 13 and the Camera Shy objective.

Walkthrough
  1. 1
    Jump down into the portal to be flung to a small ledge above your old position.
  2. 2
    Look up and shoot whatever colored portal was just on the concrete slab on the one just above it.
  3. 3
    Jump back down from the ledge and aim for the portal that is on the ground.
  4. 4
    You will be flung over to a yet higher ledge with a button.
  5. 5
    A slanted portion of the wall will come out. Put whatever colored portal was just on the concrete slab onto this one, then jump down one ledge so you can actually aim for the portal on the ground.
  6. 6
    Jump into it.
  7. 7
    You will end up on a ledge with a box on it. Grab it and jump over to the ledge with the button.
  8. 8
    Put the box on the button.
  9. 9
    Jump back down one ledge and repeat jumping into the portal.
  10. 10
    Run into the chamberlock.

Test Chamber 13 (TC13)

  1. Run forward, through the small hallway to enter a small mini-test chamber.
  2. Commentary Node: While standing in the doorway, it will be floating there, somewhere near the button.
  3. Camera Shy: Turn to face the doorway you just came out of. It is above the door. Now, you must also shoot the other portal to a different location for the camera to actually fall.
  4. Look up to see a box. Shoot a portal at the wall or floor and then one on the wall near the box. Grab the box.

There are now two ways to go about solving this chamber, the sneaky way and the proper way.

Sneaky Way

  1. After grabbing the box, instead of putting it on the button, stand on the button yourself.
  2. Aim up through the grating and into the door as far left as you can go. Shoot a portal.
  3. Now aim for the wall of the current room you are in and shoot the opposite colored portal.
  4. If you did it right, you will see a button. Grab the cube and jump through.
  5. Place the box on the button.
  6. Being careful to avoid the energy ball, jump over to the lower platform and stand on it (if you can't jump it, just portal up there by shooting a portal at the wall, another at the ground, and then jumping through).
  7. Quickly shoot a portal through the door that opens and jump off so as to avoid the energy ball.
  8. Now shoot the opposite colored portal elsewhere.
  9. Run through and re-join the walkthrough at "*".

Proper Way

  1. Put the box on the button.
  2. Drop to the floor in front of the doorway.
  3. Camera Shy: Turn around and face the doorway. The camera will be to the right.
  4. Commentary Node: After dropping from the doorway, it will be right in front of you, just beyond the energy ball receptacle.
