DARK WEB: Polybius

In the 1980s, a mysterious game began popping up in Portland, Oregon, arcades. Players walked away with a variety of strange side effects, from amnesia, to nightmares, to wild hallucinations. But the game vanished as quickly as it appeared, said to be whisked away by agents in black suits. This got many people thinking, was the game, known as Polybius, a government experiment... Or did it have more... supernatural origins?
