Portal storyline

This article describes the Portal storyline, chapter by chapter.

Test Chamber 00
Chell wakes up in a so-called Relaxation Vault - with only a small table on which lays a mug, radio, and a clipboard listing test chamber hazards, as well as a toilet and a stasis bed of some kind - and is welcomed "again" by a Computerized Voice which states that "her specimen has been processed" and that "we are now ready to begin the test proper."

Chell then proceeds through the first area and is introduced to the Heavy Duty Super-Colliding Super Button, Weighted Storage Cube, and the Vital Apparatus Vents, as well as the Material Emancipation Grills.}}
