You are the character of the story, the main character of the game. You are the hero, the defender of the city. You have a mission. Your mission is to save the world from the terrible villains that have taken over the city. You have to fight them, find their secret hideouts and fight them to the end.

The game is based on the concept of a prison, a place where criminals are sent to. But in this case, it is not a jail, it is a place where criminals are sent to, but the prison is not controlled by anyone, so the prisoners are free to move around the city. And the game begins one and a half years after the events of Arkham Asylum.

The story is a combination of the story of a prison and the story of a hero. The game has an open world, where you can go anywhere, do anything. But there are tasks that need to be completed, and the main task is to save the world.
