In Exodus, humanity has been forced to abandon Earth and establish a new civilization in a hostile galaxy. Players are the Traveler, a person tasked with exploring far-off solar systems for advanced alien technology. What the Traveler counts in days, the rest of humanity experiences in decades. With this conceit, players' choices will cause butterfly effects to ripple across humanity's new planet, particularly in the lives of their own loved ones, and the Traveler will watch these play out over generations.
