  • Jump down on the floor and place a portal on the wall next to you and go through.
  • Walk to the right, jump down from the ledge and continue to the room ahead.
  • Look up and shoot a portal on the white platform higher up. The portal must be placed near the corner on the left.
  • Put the other portal on the platform near you. Make sure it is above one of the pistons. Stand on the piston and you should go through the portal.
  • While standing on the piston, wait for the piston next to you to extend and then jump on it and then continue to the area next to it.

  • Go through the portal if the piston in front of the portal forms a temporary floor you could use.
  • Put a portal in the room behind the fence opposite of you and fall down past the pistons.
  • Go through the portal and turn to face the transportation tubes.
  • Jump down on the tube and duck. Go along the tube until you are above a similiar tube. Drop down on the tube below.
  • Place a portal as low as you can on the wall next to you. Go along the tube to the moving piston.
