Test Chamber 00
You wake up in a cold, sterile chamber, completely barren save for a bed pod, toilet, and radio. You have no choice but to heed the call of the synthesized voice over the PA as it beckons you out of the orange portal.
Walk through the circular door and into the next room. When you pass the large button on the floor, the Aperture Science Vital Apparatus Vent drops a Weighted Storage Cube at your feet. Pick it up by pressing INTERACT BUTTON, and drop it on the red button.
Head through the blast door that just opened, and proceed through the Aperture Science Material Emancipation Grid into the elevator. Congratulations—you have just solved your first puzzle in Portal. Rest assured that it will only get more challenging from here.
Test Chamber 01
Exit the elevator and drop into the glass-enclosed chamber ahead of you. Turn 180 degrees, and you see a orange portal on the wall in front of you. The blue portal that is the orange portal’s destination is alternating between three locations: the room to your right, which houses a red button; the room to your left, containing a Weighted Storage Cube; and the room behind you, which leads to the exit.
When you can see the Storage Cube through the orange portal, run through it, snatch up the cube, and exit back out.
Wait till you can see the button through orange portal in the main chamber, then run in again, depress it with the Storage Cube, and leave once more.
In a moment, you’ll be able to see the exit door through the orange portal. Proceed through it, and you’re home free.
