Complete Portal Part 22 by navigating the fire pit, redirecting energy balls, and escaping the facility. Follow our step-by-step guide to overcome the challenges.

Walkthrough
  1. 1
    Jump on the platform and shoot a portal at the wall. Shoot the other portal on the wall left of the "door" down the hallway the scaffold is heading towards.
  2. 2
    Press the button, then quickly turn around and shoot a portal down the "hall" where the scaffold is going. Wait for it to approach the corner, then go through the portal near you.
  3. 3
    Once on the scaffold, you will see an energy ball quickly hitting both walls. Quickly shoot a portal at the white wall to the left to redirect it elsewhere.
  4. 4
    Wait for the scaffold to turn the corner.
  5. 5
    Shoot a portal at the wall that looks like it will knock you off, then another at the wall to the left of the gap that is on the left of the "wall". When the scaffold comes close, jump over.
  6. 6
    While on the way to the fire, look up to see a white wall far in the distance to shoot a portal at. Shoot one there, then wait for the scaffold to extend far enough near the fire so you can shoot a portal at the right wall. Jump through the portal to end up on a walkway.
  7. 7
    Turn around and face the wall you just came out of. Shoot a portal at the top, then another at your feet. On the way down, shoot another at where you would land in order to be flung over to another area. Turn to your left to find a hallway. Run down it.
  8. 8
    Approach the stairs to have them break. Shoot a portal at the top of the stairs and another at the wall to get to the top.
  9. 9
    Go to the partially opened door and press use for it to open. Head through and up the stairs. At the top, look through the chain link fence and shoot a portal at the wall, then another at a wall near you. Go through.

Commentary Nodes:

  • Camera Shy: After redirecting the energy ball, look down the hallway to see it high on the wall at the end of the hall.
  • Commentary Node: It is floating near the "wall" around the corner. [Paul Graham] discusses adding a left side to a wall to give players a visual representation of its thickness.
  • Commentary Node: It is floating very close to the fire. [Erik Wolpaw] discusses the AI dialogue delivery and casting Ellen McClane for GLaDOS.
  • Commentary Node: Once on the other side of the chain link fence, it will be floating near the fence. [Kim Swift] discusses teaching players the rules for portal placement on new surfaces.
