Polybius is the biggest video game urban legend. An arcade game that brainwashes its players with subliminal messages. Most write it off as a glitchy version of the Atari game Tempest, but the CIA has a secret they don't want you to know about: MK Ultra. Brainwashing, mind control, LSD. Get ready 'cause this is some CreepyPasta served up Game Theory style!
- This is the first theory based on an urban legend or creepypasta.
- This is the first episode with the sixth Game Theory intro.
- This is the first episode without credits.
