Upon the timer reaching zero, a portal opens leading to Test Chamber 00. After a brief warning (which is cut out by a strange malfunction), GLaDOS counts down the last three seconds on the timer. At the 40-second mark, GLaDOS makes an announcement that the test is about to start. Upon the Test Subject's awakening, the timer above the portal starts counting backwards from one minute.
The last chamber of this course however, is connected to the Incinerator Room.īeing the first test chamber of this Testing Track, Test Chamber 00 contains both the actual test and the Relaxation Vault. The first chamber of this course is located nearby the Extended Relaxation Center from which Test Subjects are deployed from and put into temporary stasis in the Relaxation Vault. Consisting of 19 test chambers, it was first used by Chell as part of her mandatory testing. GLaDOS' testing track is the testing course featured in Portal, and partially revisited during the course of Portal 2's intro in the single-player campaign.
