This is the ninth level of the game, and takes place within a Test Chamber and the Incinerator Room. This level introduces the player to the dual-portal variant of the Aperture Science Handheld Portal Device, and the way in which two linked player-created Portals can be used to avoid obstacles. This level advances the storyline, and does not contain any significant Portal-based puzzles or obstacles. This level corresponds with Test Chamber 19 from the original Portal.
