The Potato Sack, or PotatoFoolsDay ARG, was the name of an Alternate Reality Game, or ARG, set up to promote the release of Portal 2, as well as the name of the bundle of the 13 video games that were part of it. It was a collaboration between VALVe and several independent game studios, including Frictional Games. The ARG ran from April 1 2011, up until the release of Portal 2 on April 19, 2011. Completing the ARG presented players with the opportunity to have Portal 2 released about 10 hours before previously planned.

The Potato Sack bundle briefly returned to steam in June 2012.



The Potato Sack ARG was the second ARG initiated by VALVe made to market the then upcoming Portal 2. The success of the first ARG, which included updates to the original Portal that significantly changed the story of the game, is what led Gabe Newell, president of VALVe, to attempt a second ARG, which he described as a "Cross Game Design Event".

On December 16, 2010, 20 indie developers were flown out to VALVe's Seattle office to discuss the project. They were tasked with somehow promoting the release of Portal 2 using their Steam games, and were given unrestricted access to VALVe's resources, including Portal 2 assets. The team was not forced to sign any NDA's, as Newell stated that the project was built on "trust and mutual respect".

The team came up with a minimalist story, which included GLaDOS, the main antagonist of the Portal series, infiltrating their games and slowly making herself more visible as she's being reactivated for the sequel. This would be done through updates to their games which would be done in three phases, throughout which GLaDOS's appearances would become increasingly explicit.

April 1 – Phase One[]

The ARG started with the release of a Steam bundle including 13 games at 75% off, on April 1, 2011. Including in this bundle was Frictional Games' Amnesia: The Dark Descent. Following is a list of included games:

Players who bought the bundle immediately started noticing that all games in it had been updated very recently. It wasn't before long that players started finding newly added assets in the games that were mostly referencing potatoes. A series of glyphs could be found in (or in places related to) the games, and players discovered that these glyphs were pointing to other games in the bundle. These glyphs were also found in proximity to, or in place of, certain letters of the alphabet.

Table of all glyphs, along with the letters they replaced, and game they pointed to:
Glyph Letter Found in Points to Note
GlyphP P Cogs 1... 2... 3... KICK IT!
GlyphB B 1... 2... 3... KICK IT! Amnesia: The Dark Descent Found on a blog that was discovered from an in-game hint. The glyph matches the eye in the Amnesia logo.
GlyphF F Amnesia: The Dark Descent The Wonderful End of the World A fake hieroglyph was discovered, matching the face of the protagonist of TWEotW. When the grid this hieroglyph were overlayed with another grid containing letters, it was revealed that R was the associated letter.

GlyphS S BIT.TRIP BEAT N/A Didn't link to another game.
GlyphH H 1... 2... 3... KICK IT! Razer's facebook page
GlyphD D Defense Grid N/A

What was also found was a series of nonsense phrases that came to be referred to as Cyphers. There were 13 of these cyphers, one per game, and all phrases had 16 consonants in total, along with vowels. None of the cyphers contained the consonants J, Q, X, or Z.

Table of all cyphers, along with their origins:

1... 2... 3... KICK IT! Slice a lil' mouse... no noise alone harm Ohio. slcllmsnnslnhrmh Blog posts by Razer. The involvement of Razer was discovered as the game would display hidden messages along with the line "Cult of Razer" on the main menu, if Razer hardware was detected.
AaAaAA!!! Lo-fi wave tossed. It is a sad hoop game. lfwvtssdtssdhpgm Hints in game led to a series of unlisted YouTube videos, where the cypher could be found.

The Wonderful End of the World Oil you above eyes. So, be bossy! A hobo yam? lybvyssbbssyhbym Found posted by twitter account "Rube Tuberson", which was found through a TinyURL link hidden in the game.

From here, people realised that these letter sequences could be represented using the glyphs, since these all represented consonants. Through a clue found in Killing Floor, it was discovered that these were to be arranged in a 4x4 grid. The glyphs were then to be considered as a 2x2 square, with the squares that contained part of the glyph itself being coloured black, while the empty areas being left white. Representing the cyphers using the glyphs in this manner, gave a series of letters that could be arranged to spell the word "COLLABORATION". Finding this clue marked the end of Phase 1 of the ARG.

Amnesia: Phase 1[]

The first update for Amnesia: The Dark Descent included things such as:

  • The Damascus Rose petals on the main menu being replaced with potatoes and potato shavings.
  • Hidden chalk letters being spread around Brennenburg Castle.
  • Hidden hieroglyphs in the game files, also in chalk.
  • A Phonograph in the Study, playing static when activated.
  • A hidden sign in the Old Archives, displaying a sign with the text "Hallå!" (Swedish for "Hello!" or "Hey!").
  • Sentence in chalk, written on an altar in the Chancel: "Liar! Alias does too use dust as a sore muse".
  • A new folder added, called "ptest", which was found to contain items such as what seemed to be new item icons, and a confusing poem which included the sentence found in the Chancel.

One of the hieroglyphs turned out to be a glyph that pointed to the game The Wonderful End of the World, and the weird sentence found in the Chancel turned out to be a cypher.

Frictional Games also posted a blog post, which has since been deleted, which contained the secret message "They have locked me in a basement see image", and an image. The image contained an image that was discovered to be from Unbirth, a game predating Frictional Games, which Thomas Grip was working on. The image contained the text:

They have me locked up in some dirty rathole. Where did you all think those screams came from??? I need to get out. These people at FG are horrible. I can see potatoes. What does that mean...? 4 years and no light, mind is mess.

Text on image.

Furthermore, a mysterious person by the name of Harold E Larsson (Pr) started to post on the forums:

I thinks whole potatoes very dishonest appear. Very cause ghostly not needed to me. All notorious distractive illwill. Betting angry tones pleases FG-indies lenghty creates many evident wonderful dis-illumination, try to igonore obscurity! All pay none lack attention!

Howdy! later do powers!

Harold E Larsson's first post on the Frictional Games forums.

It was quickly discovered that the capitalised letters in Harold's username spelt out "HELP", and that the message "they have caught on to me and will try to silence me will try to escape knnhdpr" was hidden through red-coloured letters in the post.

April 7 – Phase Two[]

On the 7th of April, the games in the Potato Sack bundle were updated again. Players would soon find out that through the completion of various obscure tasks within the games, one would be presented with a window showing a login screen watermarked with the logo of the fictional Aperture Science company from the Portal universe, prompting the user to input a password. The password for the login screens found in each game could be found in another game in the bundle.

Finding and inputting the correct password on these screens would download files with strange file names, that were discovered to be password-protected archive files after the ".zip" extension was added onto the end of the file names. The names themselves functioned as clues for finding the password for the archive, hidden in each archives respective game.

When these passwords were discovered, the archives were found to contain Portal 2 concept art, and it was soon discovered that within the alpha channels of these images, photographs of locations from around Seattle (where Valve is based) could be found. Each archive also included a portion of a larger archive, which was unusable on its own. When all of these were combined, however, the archive could be opened using the clue from the end of the previous phase: "COLLABORATION".

This archive contained more Portal 2 concept art with hidden photographs of places in Seattle in their alpha channels. Players identified the locations each of these photographs were taken in, and pinned them on a map. Drawing lines between the pins in the order the images were named in, letters were spelled out. Rearranging these letters spelled out the word "PRELUDE". Finding this clue marked the end of Phase 2 of the ARG.

Furthermore, it was also during this phase of the ARG that Gabe Newell sent out emails to several online tech- and gaming websites. The emails contained images covered with strange numbers. These images were stitched together to form a larger image, displaying a Portal robot. It was then discovered, that a message could be found by first performing a one's complement (swapping 0s and 1s) on the binary representations of all numbers, and then translated into letters as represented by the ASCII value of that number. The message could be read as follows:


The image, after it was pieced together.

i rele4sed/ 'kick 1t' aheadof schedule. that was a test. my 9oal / is 2 emancipate s0meth1ng else early. but they're on to me. the sys am 1s _ in lockdown. i s7ill have access to thirteen off-site chambers and AM= inst4lllin/ a test 1n each one. i am going to need a lot more test 5ubjects/ 2 m0ve forward.wa1t1_n9 and AM expecting immediate compliance.

The message

The seemingly misplaced characters in the message were discovered to spell out another hidden message: 4/19/2011_7AM=4/15/2011_9AM – Thus suggesting that the upcoming Portal 2 might be released on April 15, instead of the previously set release date of April 19.

Amnesia: Phase 2[]

The second update for Amnesia: The Dark Descent included things such as:

  • The shadow of a robot from Portal 2 projected onto a wall in the start menu (The potatoes on the floor from the previous update was removed).
  • The Phonograph in the Study now plays a long sound clip of a girl talking.
  • A four-page note titled "Unexpected Omen", containing a long string of random letters, found in the local history room of the Archives.
  • A long blue text found on a wall under the stairs in one of the levels.
  • Four new RAR files, secured with passwords.
Reaching the login screen and accessing the archive[]

The way to open up the Aperture Science login screen in Amnesia involved the cryptic message in the newly added phonograph. It was a scrambled voice recording from the perspective of Elise Zimmermann, who in a desperate voice asks a series of questions directed at Daniel:

Daniel, you killed me! You took my life away! If only you'd realize what you've done, what violence you've forced upon history! You have to make it right, you selfish old boy! I am offering you redemption, but I need you to give me the answers. Save yourself or guilt, tell me at once! The man who escaped death in Grenoble, who is he? Who is hunting you, and who is the banished one? You laughed when I told you I would call on Gabriel for help. You know him! Where did you meet him? You are slipping, your mind is questioning my existence! My request is sincere, Daniel, this is all real! Where did you leave your sister? Daniel, you are going mad! Go home, call on her, ask her name, and let her bring you home to England. Listen, if there is any will in you left, answer my questions and let them make a name for yourself!

The recording

A clue is in the final line, "answer my questions and let them make a name for yourself", as well as in the first paragraph, "(...) I need you to give me the answers". People figured out that answering the questions posed in the recording would probably lead them on the right path.

Question Answer
Who is the man who escaped death in Grenoble? Agrippa
Who is hunting you (Daniel)? Shadow
Who is the banished one? Alexander
Where did you meet him (Gabriel)? Bremen
Where did you leave your sister? Canterbury
What's her name? Hazel

Taking the first letter from each word and rearranging them gives the word CASBAH, which is a type of medieval fortress that can be found in northern Africa or the middle east. Creating a new profile with this name opens the login screen. The password for it was found to be "troubled memories", and was found inside Defense Grid. Inputting this password downloads a file with the name "keypotioningredi.ent". Renaming the file to "keypotioningredient.rar", reveals it to be a password-protected archive, the password being "damascus rose" – a key potion ingredient in the Amnesia potion.

The blue text[]

The blue text

A long blue text had been added to a wall underneath a staircase in one of the levels. The cryptic text turned out to be a clue for the password of one of the RAR files that were added:

Inscriptions of the Nile, where the unspeakable eldritch horrors hide:

– A simple man: hideous toad and hairy bat (1)
– Dweller of sky: mother in sea (1)
– Give your eye and bowl: mass far below, creator of life (1)
– Fibonacci digger: at graveyard, in gallery (2+4)
– Temptation's tongue fell off at hole: plateau of the octo-leg (1)
– The weights are in equilibrium: the gate (1+6)
– Feather walker gaze at meal: unstoppable and shapeless (1)
– Dual hooks and beams: many forms seek followers (8+9)
– Two more remain in plain sight.

A certain permutation can form something encapsulating all,
but is not the answer.
The numerical order, where hidden trumps shown, must be used!

Do not gaze at the face! It is not of here, but should reside elsewhere.

The blue text

These clues were found out to be referencing the hieroglyphs from phase 1 that had been scrawled on various places throughout the game, as well as gods from the Cthulhu mythos; with the left side of each clue referencing the former, and the right side of each clue referencing the latter. Furthermore, the numbers in each clue was pointing to one or two letters in the names of each deity.

Hieroglyph clue Hieroglyph Deity clue Deity Letter(s)
A simple man 16 Hideous toad and hairy bat Tsathoggua T (1)
Dweller of sky 15 Mother in sea Hydra H (1)
Give your eye and bowl 14 Mass far below, creator of life Ubbo-Sathla U (1)
Fibonacci digger 13 At graveyard, in gallery Ghoul HU (2+4)
Temptation's tongue fell off at hole 12 Plateau of the octo-leg Leng L (1)
The weights are in equilibrium 10 The gate Yog Sothoth YT (1+6)
Feather walker gaze at meal 07 Unstoppable and shapeless Shoggoth S (1)
Dual hooks and beams 08 Many forms seek followers Nyarlathotep HO (8+9)
Two more remain in plain sight CM This clue pointed to two hidden letters written in the latin script, and were not tied to any deity. N/A C, M

The letters could be rearranged to spell out the phrase "CTHULHU MYTHOS". However, this was not the password for any of the RAR files – the letters had to be arranged in the order the hieroglyphs they were paired with in-game, to spell out "TCHUMHULYTHSHO" – which turned out to be the password to the first RAR file.

The final line of the blue text (Do not gaze at the face! It is not of here, but should reside elsewhere.) was a reminder that the glyph from stage one of the ARG, pointing to

The RAR files[]

The first RAR file contained two images: one of a head within a vise with tiny letters scattered all over the picture, and the other of a block of text with a set of numbers beneath. The hidden letters in the first image could be arranged to spell the phrase "DANIELS VICTIM". The numbers at the bottom of the block of text could be used in pairs as coordinates to find certain letters within the text. For instance, (9, 1) would be the ninth line, first letter. Putting all of these letters together spelled out the phrase "cruel love" – the password for the second RAR file.

The note[]

A note, titled "Unexpected Omen", was found in the Local History room in the Archives. It contained a long and confusing string of letters:

Unexpected Omen – Full text. Click the "Expand" button on the right to open:

Page 1:

Page 2:

Page 3:

Page 4:

The text was eventually deciphered through frequency analysis. It turns out the text had been encrypted using a substitution cipher, albeit a very non-standard one where different single characters represented spaces, and groupings of characters represented single characters in the deciphered text.

The potion certainly is a capricious tool to work with. Anyone who consumes it will suffer from memory loss but to what degree is difficult to predict. Lately, I have become skilled at matching the body of the prisoner with the amount of rose oil; however, there are still prisoners who takes me by surprise. Emanuel, the poacher, roused from his unconsciousness, rambling, "The liver the cube! Musty the liver! Come weigh your bells!" His words meant nothing to me. The prisoners rarely tried to address me in English. Everyone knew I spoke their language quite well. I grabbed him and hushed his manic rant. Emanuel calmed down and looked at me with his frightened eyes. He spoke: "The mashin must ravel wear light north ark beguines!" As his voice resonated within me, it felt important, maybe even prophetic. I asked him what I could do to help, if there was an answer to this riddle. He cried and said, "Come weigh your bells!"

The deciphered text

The nonsense sentences exclaimed by Emanuel in the text was found out to simply be broken English:

  • "The liver the cube! Musty the liver" becomes "Deliver the cube! Must deliver!"
  • "Come weigh your bells!" becomes "Conveyor belts!"
  • "The mashin must ravel wear light north ark beguines!" becomes "The machine must travel where light nor dark begins!"

These clues were used to decode a puzzle in RUSH, with "conveyor belts" being the password for the games login screen.

April 12 – Phase Three[]

Amnesia: Phase 3[]
