The Orange Box: Portal Hints
So how do I get up onto that walkway?
1 of 7: Via the remains of the stairs that used to lead up there.
2 of 7: You'll need to portal-fling yourself at the stairs' remains.
3 of 7: Look directly up from the painted up arrow to see where to put your orange portal.
4 of 7: Fire it at the wall directly above the up arrow, as high as you can put it.
5 of 7: Then fire a blue portal at any spot on the floor and drop through it.
6 of 7: If you land back on the floor, fire a blue portal directly beneath you.
7 of 7: Keep that up until you're tossed across to the upper walkway.
