This is the eighteenth level of the game, and the first part of Chapter 3. The level is set within a dilapidated Test Chamber, and requires the player to combine the momentum provided by an Aerial Faith Plate with a Thermal Discouragement Beam and Discouragement Redirection Cube in order to proceed to the next level. The level also reintroduces Wheatley, who was largely absent during the previous chapter.
