Portal 2 easter egg outlines ARG

Portal 2 easter eggs have exposed plan outlines for the Potato Fools Day ARG, an image of the Companion Cube, and an interactive trailer for the movie Super 8.

The Potato Fools Day ARG resulted in an early unlock for Portal 2, but the clever tricksters at Valve have shown how far ahead they planned by hiding ARG notes inside the game itself. The ARG Wiki notes a hidden commentary node in Chapter 3, voiced by Adam Foster. Inside the sound file are three images that outline the ARG that just closed with the game's release.

It doesn't do much good to the ARG now that it's closed, but it's a nice little wink at fans to assure us that this wasn't made up on-the-fly. Another well-hidden easter eggs includes an image of the Companion Cube embedded in the sound file that appears upon completion of the achievement "Final Transmission."

And though it isn't technically a hidden easter egg in the game, per se, PC players were surprised to find an interactive trailer for the upcoming film Super 8 in the Extras menu yesterday. The short stage was built in Source, and lets the player explore the train and surrounding area before, during, and after the crash that drives the film's plot.

If you've spotted any other hidden goodies in Portal 2, give us a shout in the comments to let your fellow Shackers know.

      The SSTV pictures actually refer to the Portal 2 announcement ARG from 2010's Portal Radios update, NOT the Potato Fools update.

      The Super 8 Interactive teaser was pretty cool... I like the idea of a more game-like trailer/teaser... this one was done well.

      All that it needs is about 30 more seconds of that girls butt from the trailer walking in slow motion back and forth repeatedly.

        It was well done ... but I honestly felt a little dirty after having "played" it. Like I'd been coaxed into being excited over an advertisement without me knowing it.
