Make a portal on the wall behind that turret, then another But if you wantД¬arefully move forward until you see the turret, but move back quickly or it will see you and shoot at you. If you're not trying to get rid of all of the cameras for the Camera ShyДЄchievement, you can just make a portal on a wall in theДistance to get past this turret. To be on the safe side, disable it by shooting a portal below it and shooting anotherД¬ontinue on and there's a laser shining at the wall. Make a portal there, then another portal of the other color in this room, away from the laser. Carefully walk toward the laser, making sure not to walk into the beam, and look through the door until you see the far wall. Proceed through the chamber and you'll see a turret's laser hitting the wall. It will shoot like crazy and then shut off. You can walk over and pick it up, but the easiest way to get rid of it is to make a portal under it and then a portal of the otherД¬olor on a wall or the ceiling. So try to avoid that.ДЄs you enter the test chamber, there will be a turret with its back to you. Of times in a short amount of time, then you will die.

So if you do get shot but manage to get to safety quickly, When a turret sees you, it will shoot at you with a rapid fire weapon However, when they fall, they shoot a bunch of bullets for a few secondsД«efore deactivating, so you should keep your distance when making one You can even pick them up from behind, lift them, and drop them, and they might tip over. This can be done by making them fall through a portal, or dropping something on them and making them tip over. To defeat these turrets, all you really need to do is make them fall over. There are small, immobile turrets in this room that will shoot at you if they see you.
