The year is 2139. It is a future where poeple live in violent megacities. The place is Mega City One, located in The Cursed Earth: a radioactive desert wasteland formerly known as the USA. And violent "block wars" are regularly fought by citizens with machine guns. In order to combat the rising crime rate, the Mega Cities have created special police forces known as The Street Judges, who have the power to act as judge, jury, and, if need be, executioner.
