All four characters start in a dirty, downtown part of Megacity, a metropolis that covers a large part of the Earth's surface. They have to hide in this ugly area, each for their own personal reasons, and they meet during the game's storyline. Each one perceives the story from a different point of view, and with each character, you can learn more about the other ones that you can't know from the other points of view. The story is also non-linear, so it's not possible to write down the entire storyline, but the first main story mission will provide you an idea of it.​
