Local 58 is a standout in analog horror, with a sprawling history in its lore that dates back decades. The lucky few received a Steam badge along with the complete Valve pack with giftable games. With all of this Inception-style gameplay, only 1,800 players actually got all the potatoes in time for the release. Throughout the ARG, Portal 2 references, artwork, and lore were sprinkled in these other games. This included the likes of beating “TEST – For Science” in Audiosurf and completing DLC objectives in Amnesia: The Dark Descent. Where things get tricky is that each potato is found by looking through assets and completing secret challenges in select video games on Steam. It kicked off with the “Potato Sack” being released on April Fools' Day, and players had to collect all their potatoes to get the mystery prize. While this isn’t the first time an ARG has been used for marketing purposes, leave it to the same developers that made Half-Life to create one so clever just to hype up the lore and release of a game.
Potato Fools Day is a 2011 ARG created by Valve to promote the release of Portal 2.
