The Afterbirth ARG is an ARG that started with the release of the Afterbirth DLC for The Binding of Isaac: Rebirth. It ultimately led to the discovery of a new playable character, The Keeper.
Prelude
When The Binding of Isaac: Rebirth was released in November 2014, a super-secret character called The Lost was included, with a complex unlocking mechanism that was designed to be a community scavenger hunt - an ARG of its own. However, dataminers quickly discovered his existence by looking at the game code and The Lost became common knowledge in a few days, much to the disappointment of the game creators.
With the release of the Afterbirth expansion in October 2015, there was a new secret, but this one was not so easily datamined. The final reward (The Keeper) was not patched into the game until the community solved the puzzle, and many puzzle elements were not in the game at all, requiring Twitter, voice mail, and even two real-world expeditions to solve.
Generosity
The new game mode in the Afterbirth expansion, Greed Mode, is a seven-floor challenge with a boss fight against Ultra Greed at the end. On each floor facing waves of enemies rewards the player with money, which can be used to buy upgrades.
When Ultra Greed is defeated, a donation machine appears. Like the shop donation machine from Rebirth, reaching donation milestones unlocks new items and game features for future runs. However, this donation machine "broke" at 109 coins donated, rather than the expected 999.
This was fixed several days after release, allowing the machine to store beyond 109 coins. A new achievement, Generosity, was added for reaching the new cap, 999 coins. The community continued to obsess over the number 109, with such theories as "the Greed machine was fixed 109 hours after release", "the Lost character was datamined only 109 hours after Rebirth's release", and "the item Money = Power is item number 109 in the game code". The number 109 also popped up in various places in messages from Tyrone and Ed.
During this time there were several other mysterious clues in the game, including graphical anomalies when the Quarter, the Dollar, and Money = Power were hovered over in the Item Collection. Most notably, Money = Power displays the message "where are you".
The Lost Boys
Once enough people achieved Generosity somewhere around November 12, the Steam achievement icon was updated to display a piece of paper with black lines and dots on it. Taking the number of pixels in each line (with a double space meaning 0), the image translates to the number series 108 69 82 66 101 73 76. That series when converted to ASCII code becomes lERBeIL, which led to the imgur URL http://imgur.com/lERBeIL.
The image is sized 109x109 pixels, with a picture of the secret character The Lost, eight human figures, a map icon, and a quote from Genesis 30:35. Combined with some cryptic hints from Ed McMillen's Twitter, the community figured out that it was supposed to be a reference to the movie "The Lost Boys", and the next clue was out in the real world, on the Santa Cruz boardwalk. Ed and Tyrone continued to drop hints via their Twitter feeds throughout the ARG.
/u/Nirvanaguy007's brother went to the hinted location on November 13 and found a missing poster resembling the one from in the game. At the bottom is a seven-digit phone number with the last three digits torn off. On the back is written "GOD IS SPIRIT", a reference to John 4:24. The torn-off numbers are deduced to be 109, the number the community had been obsessing over.
