The Orange Box: Portal Hints
How can I knock all of these turrets over?
1 of 22: You'll have to portal your way out to their platforms and knock them over one by one. (At least, for most of them.)
2 of 22: The one to start with is the one that's on the platform nearest you.
3 of 22: You can easily knock it over by throwing a security camera at it.
4 of 22: Use portals to knock down the camera that's on the nearby wall, then go grab it and quickly return to your safe area before you get shot up.
5 of 22: While holding the camera, move toward the platform with the turret you're targeting, then jump and release the camera in order to hurl it at the turret.
6 of 22: Save before you try this, since your camera may fall down to the toxic floor without knocking the turret over.
7 of 22: The next turret you need to get rid of is the one that's on the lower of the two platforms against the right wall.
8 of 22: While staying over on the left side of the room, fire a blue portal so that it opens on the wall next to that turret's platform.
9 of 22: Make the portal as far to the right as possible so that the turret will have no chance of seeing you when you come through.
10 of 22: Next, open an orange portal on a wall near you.
11 of 22: If another turret sees you through the orange portal before you're ready to act, duck off to the side until it stops scanning for you.
12 of 22: What you need to do is quickly jump through the orange portal, grab the turret, turn and jump back through the portal, and run out of range of the turret that sees you and fires at you.
13 of 22: Then you can drop the turret you grabbed into the toxic water below.
14 of 22: Now open a blue portal as high on the wall as you can near the other turret that's on the left side of the room. (It's fairly near the first turret you knocked over.)
15 of 22: Open an orange portal on a wall near you and look through it to make sure your blue portal is perfectly lined up with the turret's platform. If not, adjust it.
16 of 22: Then relocate the orange portal to the floor and jump into it. That's the only way you can make it onto the turret's platform. (You may also need to lean on the "Move forward" key after you go through the portal.)
17 of 22: Pick up the turret and drop it into the toxic goo below, then see about portaling yourself over to the final turret's platform.
18 of 22: It's not as close to the wall as it looks, so put your blue portal just under the left end of the frosted-glass window you see over there.
19 of 22: Then turn to the concrete wall nearest you and fire your orange portal into it, about two "levels" below your own.
20 of 22: Quicksave first, then jump over to your orange portal.
21 of 22: As soon as you land in it, jump over to the platform.
22 of 22: You should make it, and may even knock the turret off in the process. If not, pick it up and toss it over the side.
