  2. Shoot a portal high up on the wall above the button then drop through.
  3. Shoot a blue portal across from the energy pellet.
  4. Shoot an orange on the wall right above the water then drop through.
  5. Shoot an orange above the button, go through the blue, then shoot another orange across from the door to the receiver.
  6. Once the pellet is past the sliding door, drop down and head for the exit.
