freedom wars

Freedom Wars (フリーダムウォーズ Furīdamuwōzu) is a Japanese action role-playing video game developed by SCE Japan Studio exclusively for the PlayStation Vita.

Set in a post-apocalyptic Earth in the year 102014,the majority of humankind is imprisoned in penal city-states known as Panopticons underground which wage war against one another. Each person is born with a 1,000,000 years condamnation, and is considered a Sinner("Togabito") that has to fight to contribute to his society; exceptions are people that can contribute by other means, like engineers, who are considered citizens. The Sinners are essentially people who can't and are sent to fight since they can't be useful to their Panopticon in another way, and try to reduce the penalty years to 0 to become citizens.

You start the game as one of the Sinners who is working to purge his sentence.
