This [[Test Chamber]] is the seventeenth level of the game. Just the really beginning of the level takes places in the maintenance areas.&lt;br /&gt;
&lt;br /&gt;
== Hazards ==&lt;br /&gt;
* [[Turrets]]&lt;br /&gt;
* [[Weighted Storage Cube|Cube Hazard]]&lt;br /&gt;

== Walkthrough ==&lt;br /&gt;
{{Spoiler|block=yes|&lt;br /&gt;
* Open the door, turn right, open the door facing you and move forward.&lt;br /&gt;
* Wait for the moving panel to extend. Place a portal in the test chamber and the other near you, then pass through it.&lt;br /&gt;
* Look up and fire the same portal as previous through the grating, then go through the other portal.&lt;br /&gt;
* Place the first portal, through the other grating, on the upper floor, then pass through the other portal.&lt;br /&gt;
* Place the second portal, through the two grating, at the bottom. Grab the [[Weighted Storage Cube]] and go through the portal.&lt;br /&gt;
