This is the nineteenth level of the game, and is set within a dilapidated Test Chamber. This level requires the player to utilise their knowledge of Thermal Discouragement Beams, Aerial Faith Plates, Discouragement Redirection Cubes and momentum in order to complete the test. The Test Chamber also introduces the ability of the Discouragement Beam to affect the position of Panels, and thereby allow access to otherwise unreachable areas.
