The first camera here is right through the door and WHAT? Live fire course designed for androids?! I’m not made of metal! Help mee!
Okay, after you disable the first turret (all you have to do is knock it over, You can pick it up and throw it and you can even drop a portal on it…), there will be a metallic hallway to your left. Take your time, as the next turret is pointed straight at you. After the metallic hallway, the second camera is also on the wall in front of you. Looking through the new door to your left, you can make a portal on the wall there and get through to cover virtually undetected. Of course, there is a small time delay between the point the turrets see you, and when they actually start firing. Technically, you could run diagonally through the laser to cover. Anyhow, portal behind the next turret, and knock it over with portals or by throwing it. Or just set it up so it can’t see you because you won’t be back this way anyhow.
The next turret is such that you can’t run past it, but you can portal past it. Don’t, however, since it’s guarding a camera, and you need that camera! You need every camera, in fact. So portal the camera off the wall, and then portal past it. You might also take this opportunity to knock over the turret by sending another turret at it through a portal. That was an easy achievement, wasn’t it? Now, after this tunnel, you’ll find your first clue that something’s not quite right in the Aperture Science facility (As if you didn’t catch on already)… The word “Help” is scrawled in blood in numerous places, and if you manage to crawl behind the panels, you’ll find what appear to be very slum-like living conditions. You can now use portals to drop these two boxes onto the turrets in the hallway. Watch out though, because they can see eachother.
Once those two turrets are disposed of, portal behind the turrets in the next room. Watch out for the ones through the door that can see you. Knock these two turrets’ heads together. You’ll find a storage closet in front of you, with a malfunctioning cube-transit tube and a pile of boxes. Feel free to portal these boxes onto the turrets in the next room. Pry the fourth camera off the wall in this room. Then use one of the boxes here on the button.
When the door opens, a turret will be looking straight out of it. Don’t tell me you didn’t see that coming. Anyhow, portal behind that turret, and then drop it back through the portal so it falls over. Pry this camera off the wall, and portal into the last room. If you do it right, you don’t even have to worry about the final turret. Just walk past it, and exit the level.

So now you know. Everyone has been talking about this “Companion Cube”. And now you have your very own! You’ll have your cube forever! Yay Cube! You can even find desktop wallpapers, avatar images, and papercraft for your companion cube on the internets, if you look hard enough.
I’m going to show you how to do this level with TWO portals. =D
Use the cube to climb to the top of the platform in the next level. Place it near a high wall, jump{with Space} to the top of the cube, and then once you’re up, grab {with E} the cube. You may need to crouch {with Ctrl} to reach the cube to grab it. Now here are some energy pellets. To protect yourself, walk holding the companion cube in front of you. The pellets will bounce off the cube, and you should be safe. Once you get to the end of the first hallway, wait until the energy pellet passes you, and place a blue portal on the far end of the hallyway.
Grab the cube again, and walk down the second hallway with the same tactics. If the energy pellet breaks, walk backwards “dragging” the cube behind you. Once you get to the end of this hallway, shoot the camera off the wall with an orange portal[if you’re not doing the 2-portal challenge]. Go through the door to your left, and shoot the other camera off of the wall with another orange portal[if you’re not doing the challenge]. Grab your cube and jump down.
Watch out for Energy Pellets! This is where they will all go. Place the orange portal on the outcropped panel down here. Run through the door behind you (the one with the closed door behind it) Do not put your cube on the first button. Head left, and put your cube on the button atop the shelf. Now go back to the first button, and wait for an Energy Pellet to pass. Step immediately on the button, and the pellet should pass through both doors, and hit the Receptor.
Now, go back and get your cube. Watch out, because the Receptor will not have shut down. They turn off in a specific order, and this is important. Use your cube to deflect the next Energy Pellet into the receptor to your left as you leave the two-button room. You may have to get your cube angled the right way, so try putting it on top of the outcropped panel, and catching it while it falls to get it angled just right. After that Receptor is happy, go into the small room to your left, and use your cube again to deflect the Energy Pellet into the Receptor.
Go back through the portal, run down the hallways with your cube, and go through the door to your left again. The lifts are now up. Jump to the first one. Get a running start and jump to the second one. Do the same for the third one. Turn right, and jump to the platform. Put your box on the button to open the door. Go through the door to press the button to open the furnace. Run back and grab the companion cube, and get ready for a tear-jerking scene as you drop it into the furnace!
You may now exit the level. Sadistic companion-cube burning portal gun person!

This level is full of fun. But if you think it’s hard now, just wait until you try it on Advanced. Okay, so lots of acid. Portal over it. Some more acid. Put a portal on the center of the ceiling to your right. Or take a break, and look to your left to find another live-in space…
So how do you get to this portal? Well, you’ve only got one reachable area of concrete, so you’re going to have to jump down into it, and hope you don’t miss and hit the acid. Also, when you come out of that portal, you have to aim, because there’s acid on either side of it. The test goes on like this… Portal to the platforms. Eventually, you should come to a closed door, and a button on a higher ledge. “Fling” yourself to this ledge with a few well-placed portals.
In here, there’s a button podium. Press the button and walk through. The turrets won’t shoot you… yet. Just stay to the left. Now, there’s an Energy Pellet Emitter here. And there are four very black marks on the wall. Fire an orange portal at one of them, and a blue portal at the point where a laser meets the wall. You should see the Energy Pellet fly through the portal and knock the turret off of the platform. Do this for all four turrets. It will make your life a lot simpler. Also; Shoot the camera.
Now, you need to get an Energy Pellet into the Receptor to power the lift. To get to the Receptor, you have to open a door. To open the door, you have to place a portal on the wall that you can reach, and one high up near the podium button. After you’ve tried this out once or twice, and you’re fairly satisfied you can do it on command, now’s the time to test out your prowess. Shoot a portal on the outcropped panel straight across from the Receptor door. Shoot another portal on one of the very-black-marks. Once you see the energy ball go through, IMMEDIATELY place your two portals at the podium button, leap through and press it. If you did it right, the Energy Pellet will enter the Receptor and the lift will be powered! Now is the fun part! You’re almost to your cube!
Ride the lift across the acid lake. Jump down to this button. This is the button that activates the doorway out of here. What you’ll need to do is place a portal on a panel that is not a part of the doorway. Press the button. If the portal disappears, that is a part of the doorway. Shoot a portal somewhere else. Now, behind you there is some concrete. Shoot the other portal there, and jump through. Make sure you have enough time to scurry back out the doorway. NOTE: If your portal is ON the doorway, you WILL fling yourself into the acid!
Now that you’ve made it back out of this infernal room, you’ll obviously be asking “Hey, where’s my box?!”… Well, you have every right to. I’ll tell you. Press this button. Run out. Place a portal on top of this angled panel. Now, look off to your right. There is a checkerboard platform down there, right above the acid. TRUST ME. Okay, now that you see it, jump down and shoot the other portal before you hit. If you were fast enough, you should fling yourself across to where the boxes are. Grab a box, and jump down to the conveyor. You now have two options, depending on how safe you want to be with your box. First you could ride your conveyor all the way across the lake of acid and put it safely on that side, then riding back to hit the button to open the door, or… you could bring the box with you when you hit the button to open the door. Either way, make sure you have the box as you go through the doorway. Now put it on the button, and you’re home free!
Oh, did I say free? I meant you have to do THIS puzzle next. There are four platforms, and one angled panel before the exit (and the final camera). Simply shoot the first platform with a random portal. Now, off to your left, there should be a deep pit with concrete at the bottom. Jump into the pit, and shoot the opposite portal at the floor before you hit it. You will fling upwards out of this portal.
This is the part I had trouble with. See if you can figure it out on your own, before I tell you…
…
Okay, now, you can’t make it to the next platform by trying to angle your way there. You have to shoot it with a portal. So at the apex of your ascent, shoot a portal at the next platform. I notice that I always come out of the next one facing backwards. So before you hit the portal below you, turn around. Now, you’ll come out, and you should see the next platform. Shoot it with the opposite color than the one you just shot. When you go through this portal, you should be looking at about 45 degrees behind you. So look toward the window to your right. When you go through the portal, you’ll be looking down to your left. Shoot a portal at that ledge. For some reason when you come out of there, you’ll be facing the ceiling. Get the jump on this by looking up as you go in. You should be able to spot the tilted panel now. Shoot the opposite color at that one, and it will fling you across to victory.
Remember to shoot the camera!
