In Story mode, '''Chamber 01''' (also known as '''Virgil-01''') is the second map of the third chapter and the first to be recognized as a test chamber.
This chamber also has the only known Ratman's [[Den]] in the game (which is related to the achievement [[#Achievements|Under the Stairs]]). The map is divided in two tests.
The first one makes use of [[Goo]] and introduces the player to the [[Excursion Funnel]]s. In Advanced mode, it also introduces [[Laser Field]]s.
The second one, in Advanced mode, makes use of [[Propulsion Gel]].

==Trivia==
* A [[Weighted Companion Cube]] can be found in some debris at the start of the map. Attempting to pick it up will immediately fizzle it and give the achievement [[#Achievements|Forever Alone]].
* [[Hoopy the Hoop]] can be spotted in a secret room accessible by making a portal through a broken window. This is followed by Virgil, saying “people (are) obsessed with a silly hoop”.
