Portal 2 Easter Eggs

Though they make some of the most powerful and emotionally-affecting games around, the designers at Valve still love a good joke. With this sensibility in mind, it becomes worthwhile to comb their games for hidden humor and Easter Eggs. The Portal series is one of the most irreverent in the Valve stable, and its first installment featured a number of amusing hidden features. Portal 2 is similarly seasoned — check out the videos below. For more Portal 2 gameplay and advice, consult our full walkthrough.

Testing Chamber 20 Glitch

Band of Turrets

P-Body Sneaking Around

“Door Prize” Achievement

The Borealis and the “Ship Overboard” Achievement

“Portrait of a Lady” Achievement

“Exile Villify” by The National

The band The National has written and recorded a song just for Portal 2, and you can find it in your adventures in Chapter 2. It’s located in the second Rat Man den you come across, playing on a radio there. Watch the video below to see how to find it, as well as all the Rat Man dens.

Rat Man Transmissions
In a few key places are special audio signals you can hear through radios. These are signals sent by Rat Man, a character you never meet in Portal 2 who escaped GLaDOS’ testing chambers and lived in the walls. Get more backstory on Rat Man from Valve’s comic, and find and decode his transmissions with our Rat Man Signals Decoder Guide.

Extra Dialog
Just about every character in the game will spew all kinds of extra dialog lines at you if only you’re willing to let them. Any time a character gives you an order or asks you to advance to the next section, just sit tight and listen to them. They’ll almost always just keep talking for quite a while, and the lines are often hilarious.

Aperture Science posters
Keep your eyes peeled in the Testing Spheres in chapters 5, 6, 7 and 8 for various posters from Aperture about procedures, information and emergencies. When you first hit the Repulsion Gel test, for example, you can read about how it was originally designed as a pudding-form dietary supplement, until it was involved in many lawsuits. Other posters encourage testers to work safely to avoid investigations that will slow down Science, and explain what to do in the event of a rogue A.I.

Personality Sphere Quotes
Here’s the Space Core’s dialog.
And here’s the Adventure Core.
And finally, the Fact Core.

Didn’t enjoy this.

Don’t want a bunch of stupid videos. Want real text, the kind which you can print out.

Thanks for these.

Thanks for these. I knew there was something about that turret in the grate. More places to explore: Valve did a great job with this game.

Hey, just wanted to say I found Atlas hiding in Chapter 2 Chamber 2, if you rush to the location of the redirection cube as soon as possible you’ll see him hiding behind a panel right behind it before he runs off

Hmm… Alex: I’ve seen that part a couple times & I could have sworn it was Wheatley.

Hey, there is one more Easter Egg, if you play through the game with commentary, there is one level where one of the commentary bubbles plays a transmission like the ones in the Rat Man’s dens. Can’t recall which test chamber, or even which chapter, but it was fairly early.

wait a sec the guy who writes all the stuff on the walls glados has the same brain as his wife because she says ,on portrait of a lady achievement ,hmm those two look familiar…….

Finish the game man. GLaDOS is Caroline in a computer, which is why they are familiar. Cave Johnson is the man with her and he isn’t her husband. He’s her boss but it is hinted, but not elaborated upon, that they are at least dating. it was Doug rattmann who wrote on the walls. He was an employee forced to run the tests an was trapped in the facility when GLaDOS went haywire. he followed chell (who has nothing to do with Johnson or Caroline, they just provide more back story) during her tests in portal 1, but is presumed as dead in portal 2 because portal 2 took place centuries later and rattmann had been shot by turrets. So no, you are VERY wrong

so apparently, gamefront didn’t see the poster where Chell was wearing a lab coat and holding hands with Cave Johnson.

In that last Rat Den location (Chamber 17) you can shoot portals through the fan grate and gain access to behind-the-glass locations.

They missed another hidden content moment. When on the “Turrent Redemption Lines”, look for the turrent on the second conveyor that says “I’m Different”. Pick it up and take it with you. It will say “Thank you”, then periodically spit out stuff starting with a bit about prometheus (Greek Mythology), warn you about not getting mad about lemons, and finally telling you GladDOS’s real name is Carolyn. I don’t know if this is just additional dialog or an Easter Egg, but no one seems to mention it.

At the end, GLaDOS addresses Chell (in the Huge Italian Turret Opera) as her ‘Baby’ and ‘child’. Caroline *is* GLaDOS. So, Caroline must be Chell’s mother. But who’s the father? Time to call Maury, I suppose.
