The Orange Box: Portal Hints
How can I get the orb to its receptor?
1 of 13: With a lot of portals.
2 of 13: Remember that any portals you have set will vanish when you move through any force field.
3 of 13: Move into the area that includes the wall that the energy orb bounces off of, staying close to the force field you just came through.
4 of 13: Wait for the current orb to pop, then immediately fire a blue portal onto the wall where the orb bounces.
5 of 13: Before it can get to the blue portal, put an orange portal on the perpendicular wall to the right of it.
6 of 13: That'll guide the orb through the force field you're standing next to and into the area with the raised lift.
7 of 13: As soon as the orb comes out through your orange portal, go through the force field and into the area the orb is heading for.
8 of 13: Quickly put the orange portal on the wall the orb is going toward, and then the blue portal on the wall right above the raised lift.
9 of 13: As soon as the orb comes out of your blue portal, enter the room with the receptor and fire the blue portal onto the back wall where the orb is heading.
10 of 13: Before it reaches that portal, fire the orange portal onto the ceiling directly above the receptor.
11 of 13: If you're fast enough, you'll be able to get the orb into the receptor before it can pop.
12 of 13: If you fail the first time, you may at least have a new black mark on the wall to help guide your portals the second time.
13 of 13: In fact, you may want to purposely fail the first couple of times, getting the orb a little farther along each time, in order to gain all the guiding black marks you need to get this done.
