By powering up the mysterious Time Rifts that opened in the wake of the cataclysm, each Path is able to reach back to specific moments in their past. Doing so can greatly speed up their progress, but too much meddling may endanger the time-space continuum. But progress is more important than ever before: if the mysterious message arriving through the Time Rift is to be believed, an even more terrible cataclysm is looming on the horizon: an asteroid bearing the mysterious substance called Neutronium is heading towards Earth.
The game is played through a series of turns called Eras, with past ones reachable through time travel later in the game. Players assume the roles of iconic leaders of the four Paths, striving not only for the supremacy and well-being of their people, but also their survival. After the fourth Era, an asteroid impact shakes Earth, threatening to destroy the World Capital, Earth’s last independent city. The Paths should prepare for the coming cataclysm, and when the time comes, take their part in evacuating the collapsing Capital. In the end, one of the Paths will be the new home to the reformed World Council, and lead humanity into a new future.
