This is the first level of the game and serves as both a tutorial and introduction. The first part of the level takes place within the interior of an Aperture Science Relaxation Chamber, and introduces the player to gameplay fundamentals such as looking with the mouse, moving and activating objects. The player is also introduced to both the Announcer and Wheatley at this time. The second part of the level provides a more detailed look at the Aperture Science facility while the player is transported to the first Test Chamber. The final part of the level takes place within a dilapidated Test Chamber, and introduces the player to Portals, as well as the Weighted Storage Cube and the way in which it interacts with Heavy Duty Super Colliding Super Button. When the first Test Chamber has been completed, the player will encounter the Emancipation Grill and exit through the Chamberlock.

Trivia
The painting Chell is instructed to observe changes[1] between her first and second wakeup. Additionally, it bears a striking resemblance to Lakeside Hideaway by Thomas Kinade.[2]
During the early phases of Portal 2's development, the Relaxation Vault was to resemble an island, as seen above.
