You have built an entire world steeped in mystery and lore. Within this world enters a solitary figure, causing disruption wherever they go. Watching from afar, a shadowy entity convinces this figure to do their bidding as they battle for survival. Friends appear and disappear, enemies grow in number and aggression, questions arise as to what, exactly, would be the "right" thing to do. Madness, loneliness, desperation and greed. These are the themes of the videogame you have created, this is BioShock.
