Portal 2 Chapter 9 Finale

This is the sixty-first and final level of the game. The level takes place within the maintenance areas of the Aperture Science facility, as well as Wheatley's Lair, and features Conversion Gel, Repulsion Gel and Propulsion Gel. Bombs and Neurotoxin are present as the primary hazards.

The credits scene and the scene with Wheatley and the Space Sphere are actually part of what's known as Chapter 10: The Credits, even though there's no title to that chapter in the game apart from on the main menu.
