To quote the intro of Fallen City, Channel 4 and Big Robot's educational puzzle/real-time strategy game: What is a city? It is a machine; a machine for living in. But all machines can break down. The inhabitants of Fallen City (Angries) have become distracted by their individual lives and dreams and have let the once gleaming metropolis fall into disrepair. Frustrated by their inability to live the lives of fame and fortune they were told could satisfy them, many of the Angries fell into boredom or rage... and the city sunk ever deeper into its gloom. But broken machines can be fixed, right?
