The Orange Box: Portal Hints
How can I get this orb into its receptor device?
1 of 8: Have you seen the receptor yet?
2 of 8: It's on one of the walls in the main portal gun room.
3 of 8: It's on the only wall that the portal gun won't fire at.
4 of 8: However, the portal gun will fire at the wall that's directly opposite to it.
5 of 8: Once you get into the energy orb's room, notice where the orb hits the wall and makes a black mark.
6 of 8: You'll want to fire a blue portal at that mark when you know the orange portal is on the wall that's directly across from the orb receptor.
7 of 8: Watch through the blue portal you entered through until you see the receptor across the room, then quickly turn and fire a portal at the orb's black mark.
8 of 8: Or you can fire a portal at the black mark at any time and then stand and wait for an orb to eventually reach the receptor.
