Portal 2 Hints

How can I get to the fourth floor?

  • 1 of 7: Go through the force-fielded doorway and check out the gel leak area.
  • 2 of 7: Before you can get to the fourth floor, you'll have to figure out how to get onto this area's upper floor.
  • 3 of 7: Notice that when you were flung onto the upper floor, you bounced off a repulsion gel leak and landed on a portal-friendly floor section.
  • 4 of 7: What if that portal-friendly floor section also had repulsion gel on it? Maybe then you'd have bounced all the way over to the main structure's fourth floor.
  • 5 of 7: After that's done, drop down to the lower floor and move the orange portal to the slanted surface.
  • 6 of 7: Put the blue portal at the top of the vertical surface, then make the run again.
  • 7 of 7: Keep the "Move Forward" key pressed down until you make it all the way across to the fourth floor.
