Portal/Chamber 16: Difference between revisions


Take out the first turret by hand, but pick it back up after it’s dead. Use it as a half-shield, and [[Portal/Tips and Advanced Techniques#Cube Throwing|toss it]] at the second turret when you are close enough. From here, proceed as in the silver method until you have the button pressed. Notice that you can actually see the second fence through the first fence.

Here is one possible gold method. Shoot a portal on the ground at the door while you wait for the door to open. As soon as it does, shoot one at the top part of the wall so that you fall through, probably knocking over the turret in the process, and can easily continue on. Put a portal behind the next turret, and then across the next hallway. Now for the two turrets facing each other, place a portal on the X above the nearest one (this should be happening around the 30 second mark). Walk towards the two cubes and shoot a portal underneath them so that one falls through to knock out the turret, but grab the other before it falls. Then just use it as a shield as you run towards the other turret. When you are close enough, [[Portal/Tips and Advanced Techniques#Cube Throwing|toss the cube]] at the turret, and quickly shoot a portal at the far corner of the next area, coming on through. Place a portal on the wall behind the turret in the button room that can probably see you right now, and another on the floor below the turret (in that same room) that is actually on a portalable floor. This will hopefully knock out both of these turrets. Now put a portal underneath you so you come out the other floor portal. Quickly run onto the button, shoot a portal on a wall past the first fence (past both fences if you get lucky), and come through before you die from the third button-room turret. Proceed to the exit (another portal past the second fence if necessary).
