Thinking With Portals, Doing Science

Images on which portals to enter and in which order to get the achievement.

Introduction

Welcome!

I considered showing where portals exit to as well, but when I looked at it, it was too cluttered to see properly, even for me. So I just left it as just showing which portals to enter when given a choice.

Good luck.

Screen 1

As you enter each portal, just hold down "right" until you appear at the bottom half of the screen again.

Screen 2

Enter portals as shown. Portal 3 goes through the wall to the adjacent portal, just hit the bottom arrow, then move to next screen.

Screen 3

Portal 6 takes you near the door in the bottom right.

Screen 4

Simply hit the first jump star, and let it cycle through the portals.

I believe it's a level from this DLC called "An Evil Portal Mess".

What level is this

[Jepp]

No worries, thanks!

Weird, I got it now. But I reinstalled the game. Thanks for the guide.

[Jepp]

Strange. I'm not sure there's any way I can actually test this out since I already have it. If you find out the correct way, I'd love to hear so I can fix this guide up.
Thanks!

Does not trigger the achievment for me...
