About the Game

There Are Two Kinds Of People In This World: The Rulers And The Ruled

Though born and raised in a strict, luxurious utopia, your time as a police officer is sadly cut short when you're framed for the death of your own parents. Following your exile to the destitute, steampunk districts below that utopia, it's up to you to try and clear your name if you ever hope to return. Yet the city you've been sentenced to is much different than the lawless, barbaric place you've been led to believe it is.

As you learn more about the world and its harsh class divide, you'll come to question your old beliefs, and it will be up to you to decide what kind of life you want for yourself in this world.
