The Orange Box: Portal Hints

How can I get an orb into receptor #3?

  • 1 of 13: This receptor is way at the back of the area, past two button-opened doors.
  • 2 of 13: The first thing to do is figure out how to hold those two doors open so the orb can get through them.
  • 3 of 13: You only have one companion cube, so it's pretty clear that you'll have to hold one of the doors open by standing on its button.
  • 4 of 13: Since the button for the second door is up on a platform you can't jump to on your own, it's clearly the one for your cube to hold down.
  • 5 of 13: Carefully lift the cube up and over the button, then drop it.
  • 6 of 13: Now go about redirecting the first orb corridor's energy orb into this area.
  • 7 of 13: Return to the room between the corridors that contains the two orb firers.
  • 8 of 13: When it's safe to do so, look down the corridor that still has an orb bouncing along it.
  • 9 of 13: Fire a blue portal so that it hits the wall at the other end of the corridor where the orb usually bounces.
  • 10 of 13: Return to the main lift room and drop down, then open an orange portal on the extended wall section that faces the two button-opened doors.
  • 11 of 13: Now go over to the button that opens the first door, being careful not to get hit by the orb along the way.
  • 12 of 13: Crouch down and move to where you're at the very left or right edge of the button. That way you can hold it down without the orb hitting you.
  • 13 of 13: Wait in that position until the orb comes by and enters receptor #3.
