&lt;br /&gt;
These chambers form the fourth level of the game, and take place within two separate dilapidated Test Chambers. The two Test Chambers introduce the concept of using multiple [[Weighted Storage Cube]]s in conjunction with intermediate [[Portals]], as well as utilising the [[Aperture Science Handheld Portal Device]] to obtain objects that would otherwise be inaccessible. These two Chambers correspond to Test Chambers [[Portal Test Chamber 04|04]] and [[Portal Test Chamber 05|05]] from the original [[Portal]]. {{Spoiler|Chamber 04 features a [[Doug Rattmann|Rat Man]] den, which is decorated with a number of his trademark murals.}}&lt;br /&gt;

{{Spoiler|block=yes|&lt;br /&gt;
=== Chamber 03 ===&lt;br /&gt;
* When entering the chamber, observe the Weighted Storage Cube falling into the pit. Either fire a portal below the cube, or jump down and then fire a portal at a wall and then carry it through, to bring it to the upper level.&lt;br /&gt;
* Place the cube on the [[Heavy Duty Super-Colliding Super Button]]; proceed through the door into chamber 04.&lt;br /&gt;
=== Chamber 04 ===&lt;br /&gt;
* Observe the orange portal on the platform across the room; place a portal and walk on to said platform.&lt;br /&gt;
* Place a portal on the opposite platform; it is now possible to acquire the cube through the orange portal. Place the cube on one of the buttons by the door.&lt;br /&gt;
* Opposite the door will be a pit containing a cube; fire a portal below the cube at the bottom of the pit to place it on the platform with the orange portal. Follow the cube through this portal or through a new portal on your current tier, whichever is most convenient, and place the cube on the remaining button and walk through the door.&lt;br /&gt;
* Look up to observe an orange portal through the glass; place a portal on one of the surrounding walls and walk through it to land on top of the glass.&lt;br /&gt;
* Turn around and walk through the destroyed section of wall to reach the [[Chamberlock]]. Inside this wall section is a staircase that leads to a [[Doug Rattmann|Rat Man]] den.&lt;br /&gt;

*In Portal 1, these chambers are separated by an elevator, but in Portal 2, this is retconned to Chamber 4&#039;s entrance being merged with Chamber 3&#039;s exit.&lt;br /&gt;

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. {{Spoiler|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]].&lt;br /&gt;
