Portal 2 walkthrough and video guide

Chapter 1 | Chapter 2 | Chapter 3 | Chapter 4 | Chapter 5 | Chapter 6 | Chapter 7 | Chapter 8 | Chapter 9


Chapter 2 - The Cold Boot


Test Chamber 01


After GLaDOS activates the laser, fire a portal where it meets the floor. Walk to the back of the room and stand on the actuated platform beneath the exit. Fire your second portal onto the ceiling above the laser receptacle (an orange glow indicates where to place it). The platform will rise, allowing you to exit the chamber.


Test Chamber 02


 

Use a couple of portals to acquire the Discouragement Redirection Cube in the rear left side of the room. Pick up the cube, and cross to the other side of the laser. Position the cube such that it directs the beam into the receptacle, making sure that it is on a surface capable of receiving a portal later. Walk up the newly formed stairs to the exit. Fire a portal beneath the cube, and one on the floor next to you, and grab it. Place the cube on the button to continue.


Test Chamber 03


Portal up to the tall platform with the Discouragement Redirection Cube on it. Place a portal above the actuated platform in the middle of the chamber, and take the cube through it. Use the cube to aim the laser at the receptacle, and leave it there. Return to the elevated platform where you found the cube and fire a portal at the spot where the second laser hits the wall. Fire another portal on the floor of the platform, so that it hits the receptacle on the ceiling. Walk through the door!


Test Chamber 04


After entering the chamber, use your portals to direct the laser through the wall to your left, such that it hits the receptacle on the right side of the room. The platform in the back will begin to move - when it reaches the left side, move one of your portals to stop it. Portal over to the platform and press the button to release a cube. Bring the cube onto the moving platform, and use your portals to start it up again. Pick up the cube and carefully use it to block the laser as the platform moves past it. Place the cube on the button.


Test Chamber 05


 

Use the Aerial Faith Plate to catapult yourself to the other side of the room. Press the button to release a cube which will bounce up and down in the center of the room. Time your next Faith Plate jump so that you can grab the cube in midair as you fly by it. Once you have the cube, place it on the button by the exit, as usual.


Test Chamber 06


The Aerial Faith Plates in this chamber will catapult you across the entire room, but only as long as you place a pair of portals in the two angled platforms on the far right side. You can't see them immediately after entering, so move toward the left until you're able to hit them with portals. Either that, or trust yourself to hit them in midflight.

Once you make it to the other side, press the button and several pieces of garbage will be launched along the same path you took. Play with it if you want (the radio plays a familiar tune...), or ignore it and press the button again to release a cube. Facing the button, you will see a portal-accepting surface on the ceiling to the left. Once you have the cube, fire a portal onto that surface, and another on the floor near you. Drop the box through your portal, and onto the button below.


Test Chamber 07


 

GLaDOS will mess with you for a bit, but after a couple tries, you'll have a cube to work with. Use it to block the laser, which will lower a platform. Stand on the platform, and raise it again by moving the cube with a couple of portals. When you reach the next level, you'll see two angled platforms. Fire a portal on the platform on the right. You'll need the cube again for this, so fire another portal beneath it to reacquire it.

Now you need to jump through a portal on the floor to launch yourself out of the angled platform and onto the platform which houses the button. Take the cube with you when you do this, and place it on the button to activate an extension on the next platform. Leave the cube there, and repeat the jump, except through the angled platform on the left this time.

GLaDOS will tell you that the Emancipation Grill in this chamber is broken. For an easy achievement, fire a portal into the wall after you walk through the exit door, then return, pick up the cube, and walk through a portal and back into the exit with it.


Test Chamber 08


Once GLaDOS creates some stairs for you, walk up them and through the large Emancipation Grill. Press the button to release a Discouragement Redirection Cube on the other side. It cannot be taken directly through the field, so walk over to it, and fire a portal through the small hole in the glass, and onto the wall on the other side of the field. Fire another portal nearby, and take the cube through it. Use the cube to aim the laser at the switch, then leave it and walk through the exit.

    Help! im stuck in 1 Chapter, cant do orange portal with right mouse click.. Only blue comes up. Frustrated. I have new imac, maybe mouse settings are not right. Help me to go on, thanks.
  • charlesmonster - June 16, 2013 2:44 p.m.

    I have a mac to and have had this problem, go into System Preferences and select "mouse." Then click the box next to "Secondary click." Then shoot all the orange portals you want :D

    I was really stumped in "Test Chamber 19". Thanks!!!
  • gnokes - May 15, 2011 8:36 a.m.

    I AM SO FRUSTRATED!!! I am on chapter 6 the fall, I believe the 6th room, right after you drop the box that jumps all over the place. I get in the elevator to go upto the next room, when as soon as the elevator goes up the screen goes black but never comes back on. The system is not frozen I can still hear footsteps (even though it doesnt sound like I can move very far), the sound of glass breaking, and the portal gun firing, yet I can not see anything. No matter where I try to save the game, nor going back and completing the prior level again I get the same black screen that I cant get passed. I've been to a couple other blogs and nobody else seems to have this problem but me. The disk is brand new and no scratches, and this has never nor does happen on any other game.

    Some of these tests are so easy that you'll just think "Why didn't I think of that in the first place?!" But even after a swift kick in your own pants, you feel like a genius. Also, any word if you'll do a little cheat sheet for the trophies/achievements?
  • BoltActionRevolver - April 23, 2011 4:38 a.m.

    I thank you for the video walk though Mr Wilde, "Mann" Tyler. The two places I got stuck, it helped. I do appreciate the lack of ending also. Let those who want a spoiler for it wait till some one beats it and posts it
  • batman5273 - April 22, 2011 9:56 a.m.

    What a great guide, I tried not to use it, but there were some WTF areas. And then after I watched the video, I could have kicked myself in the ass on how simple it was to solve. Great job, Tyler!

    Thanks!
  • zigs - April 21, 2011 3:30 p.m.

    @VMPSaberwolf it's a trap! But you get an achievement/trophy for it
  • VMPSaberwolf - April 21, 2011 10:28 a.m.

    In Chamber 21, when you are given the option to flee after Wheatley opens a wall for you, there's a part where Glados reveals a test which I bypassed and kept running with Wheatley. Has anyone tried crossing the bridge Glados makes to get to that test? What happens if you do?
  • FreedomPhantom - April 21, 2011 1:31 a.m.

    I am making this game take as long as I can... That's very hard! I'm on chapter 6 right now and I am absolutely in love with this game. I haven't even checked out co-op mode yet though! p.s. @Tyler: I've only watched a couple of videos but I'm very impressed! A full walkthrough so soon! I don't care if you haven't finished all of the writing part of it, this is excellent! Not that I want to use a walkthrough on any part of the game that I haven't played yet... unless I'm stuck on it for more than say... three days? :) p.p.s @Tyler: It makes me proud to be a gamesradar fan when the journalists (you) participate in the forums so much. Just saying!
  • Asmodean - April 20, 2011 9:59 p.m.

    Beautiful game, just finished it now... the characters, puzzles, jokes and end 'battle' just beautiful... I have to know how VALVE does it, I mean how the heck did they train me to think the way they wanted; the moon, The Moon, in no other game would have have looked up and thought 'of course the moon'. I'm stunned...
  • Tatts4Life - April 20, 2011 1:43 p.m.

    Proud that I've beaten the game without having to use the walkthrough. There were a few spots I had trouble on. @GamesRadarTylerWilde are there any clues in the videos on how to get some of the harder trophies like the rat man one?
  • quincytheodore - April 20, 2011 6:22 a.m.

    I scrolled straight for comment section while, "Ahh, aghhh.. Spoiler.. don't wanna see.." I wonder how long I'll last before seeing this.. I didn't use in the first one, self-esteem +1, just because my friend didn't finish it. Hopefully, it stays that way.
  • WelcomeGhosts10 - April 20, 2011 2:47 a.m.

    Not going to look at these, because I don't want spoilers, but wanted to comment and say good fucking work Tyler, goodness!
  • GamesRadarTylerWilde - April 20, 2011 12:05 a.m.

    @smashpro1 I don't think so.
  • smashpro1 - April 19, 2011 11:41 p.m.

    Can Cave Johnson own any harder?
  • Tatts4Life - April 19, 2011 10:33 p.m.

    @GamesRadarTylerWilde after my post I was able to figure out what to do. So far I haven't had to ;ook at the videos. I'll probably go back and look to see if I missed any trophies. Loving the game so far.
  • Roofmonkey - April 19, 2011 9:37 p.m.

    Just finished the single player I recommend everybody to play it, it's awesome! Sorry Tyler, didn't need your walkthrough. :P
  • GamesRadarTylerWilde - April 19, 2011 8:44 p.m.

    @Tatts4Life How convenient, we just posted that chapter!
