Portal/Chamber 18: Difference between revisions

'''Part 1 - Drops and Flings''' : If the normal walkthrough is executed promptly and perfectly, you will take about thirty seconds to get from the entry chamberlock to the button outside the turret room.  A second or so can be shaved off by portaling along the hallway instead of walking.  Using the method described here, you can cut that time down to twenty seconds or even less and impress your noob friends with your ninja skills.

Step out of the chamberlock and immediately shoot the orange portal at the most distant section of portalable wall that you can see, which will be on the left side of the room and ''below'' the level at which you are standing.  Turn to the wall and place the blue portal there.  Now, use [[Portal/Tips and advanced techniques#Peek-a-portal|peek-a-portal]] to move the orange portal to the ceiling over the ''second'' platform (that is hidden around the right hand corner).  The exact placement is important and you will have to practice it until the next move works out properly.  The portal has to travel a long way, so you will have plenty of time to pull back.  Don't go through.  Instead, move the blue portal to the floor.  Then walk around the blue portal until by looking through it you can see the platform with the three-dot symbol on it.  Crouch, aim the portal gun slightly high to hit the platform well to the left of the symbol and drop through the blue portal.  As soon as you're through, fire the orange portal, then immediately look down and place the blue portal underneath you (on the platform with the two-dot symbol).  When you come up, turn slighly to the right and you will see the door to Part 3.  In mid-air, move the orange portal to the middle of the protruding section of wall above the door and look down to place the blue portal underneath you.  This fling will take you right over the button and into the tiny room beyond to start Part 2.
