Polybius (urban legend)

Polybius is an urban legend, a thing that may not exist. The legend says that playing the game would produce intense psychoactive and addictive effects in the player. The few arcade machines were said to have been visited periodically by men in black for the purpose of data-mining the machines and analyzing these effects. Supposedly, all of these Polybius arcade machines then disappeared from the arcade market.

This urban legend has persisted in video game journalism and through continued interest, and it has inspired video games with the same name. The legend may have come from on coinop.org, a website about arcade games.

The only screenshot is the title screen. It was supposedly developed by a "Sinneslochen Inc." in 1981.
