Chapter 9: The Part Where He Kills You

Surprise in Test Chamber 17

As Wheatley confronts you with his spikes, fire a portal through the broken wall behind him. After a moment, white gel will begin dripping onto another surface. Fire a portal beneath the drips, and a glob will fly out of your other portal and land on your platform, giving you a chance to escape. Run!

When you reach the end of a broken catwalk, look up - there are two surfaces on the wall. Fire a portal onto the further, higher surface, then jump off the end of the catwalk and fire your other portal beneath you.

Run For It

Portal through Wheatley's "trap" and continue running. When you reach a row of functional turrets, use the Excursion Funnel to pick them up and send them levitating through the windows they're facing. Jump into the funnel, and ride it to the next catwalk (try to avoid being crushed).

When your path is destroyed by a falling pipe, use the Propulsion Gel it left behind to jump over the gap. Your path will end at the receiving end of a turret brigade. Look up - you can fire a portal through a broken window and into another room. Use the dripping Propulsion Gel in the room to destroy the turrets, then portal across the room to the Faith Plate and use it to jump to the next catwalk.

Death Trap

When you arrive in the first room, use the hole in the cracked window to shoot a portal beneath the bomb-dropping tube. Fire another portal high on the wall in front of you, and a bomb will fly through, breaking the pipe and releasing the gel. Escape the room by placing a portal on the floor.

When you reach the conveyor belt, Wheatley will attempt to kill you. Jump off of the belt and walk up the stairs - from there, another bomb pipe can be used to break a Propulsion Gel tube on the far side of the room. Once it's leaking, place a portal at the end of the conveyor belt to cover it with gel - now you can run against the direction of the belt, and jump through your portal to escape.

In the next room, you'll need to use more Propulsion Gel to accelerate down the long hallway and through a portal placed beneath the Excursion Funnel.

The Final Battle

When the fight begins, stand in front of the tube of white moon goo. One of Wheatley's bombs will hit it, spraying it everywhere. To damage Wheatley, redirect his bombs into him through portals placed either beneath him, or on the platforms surrounding him - observe the formation of his bomb-proof shields to know which direction to attack from.

When you score a hit, GLaDOS will provide you a corrupted core. The first core will appear above the catwalk - just portal up to the structure and run over to it to grab it. The catwalk will break, and tube will spray out Repulsion Gel. Bounce up to the flashing red light on Wheatley to install the core - when you're close enough, it'll latch on automatically.

The second core will appear over the section of the catwalk which broke away. Run down the catwalk, jump off of it, and use the Repulsion Gel to bounce over to the other side, where you can grab the core as it swings by. Attach it to Wheatley the same way you attached the first core.

The third core is trickier - it crashes through the ceiling next to the Propulsion Gel tube. Fire a portal into the ground below it, then run down the strip of Propulsion Gel and through the wall to launch yourself up to it. Once you have the core, use another patch of Repulsion Gel to bounce up to the connector. Now all you need to do is press the button...

    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.

    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!!!

    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!

    @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?

    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!
