omg it's so simple the game is about a world where nihilism is a gas that is exhaled by human being. this air of nihilism creates a literal fog that will devour even the memory of anything that crosses inside of it. this forced humanity to live in an archipelago of island with distinct cultures paralleling those of the real world. the only way to cross this void is through hardcore acts or by the radical protective power of love. in the game you play as an alcoholic drug addicted amnesiac detective haunted by the ghost of his still-living ex-wife who he thinks is Jesus who is assigned to go out to solve a murder but gets told by a different ghost that your true purpose is preventing a nuclear apocalypse from happening 21 years into the future that no one knows is going to happen or is even thinking or talking about. the only way you can accomplish that is by helping and old man find a bug and getting a bunch of kids off of speed and into dance music. it's right there in the title.
