This is the fifty-seventh level of the game and the first part of Chapter 9. The level takes place within an Aperture Science Test Chamber and the maintenance areas of the facility, and features the Aerial Faith Plate, Excursion Funnel and Conversion Gel. Crushers are present as the primary hazard in this level.

Hazards

Walkthrough

  • Use the Aerial Faith Plate and wait until you get on solid ground.
  • Fire a portal on the Conversion Gel and the other one on the wall next to the monitors.
  • A drop of Conversion Gel will paint your platform. Shoot either portal under yourself to get to the catwalk. It doesn't matter which, as for instance you use a blue portal above the catwalk and then fire one underneath, the orange one will be moved over.
  • Continue walking along the catwalk.
  • Stop when you get to the end of the catwalk and shoot a portal on platform below the catwalk.
  • Place the other portal on the wall on the right higher above.
  • Jump through the portal on the platform.
  • Walk along the catwalk.
  • Stop when Wheatley uses the Crusher.
  • Put a portal on the wall on the left to the catwalk further away.
  • Go back a few steps and fire a portal on the wall and go through the portal.
  • Run through the Emancipation Grill on the left.

Fake escape

Near the start of the excursion funnel, there's a girder that looks like a possible escape from Wheatley's clutches. However, not only doesn't it lead to any portalable surface, it doesn't actually exist in the first place: Any object, player included, passes right through it.
