Five hundred years after the events of Final Fantasy XIII-2 where Lightning is tasked with saving the souls of humanity in a world heading for destruction. The world-driven concept with a #34;doomsday clock #34; element that determines how much time is left before the Apocalypse. The player is initially given seven days to explore the world, but this can be extended to thirteen days by completing sidequests. Chronostasis stops the flow of time momentarily to give the player a chance to explore, and playing in the Easy Mode has no time-punishment for fleeing battles. A countdown timer indicating the time left until the end of the world is displayed in the upper-right of the screen. An in-game day lasts twenty-four hours, like in the real world, as after the Day of Ragnarokin Final Fantasy XIII, two hours were lost. This is to make up for the clocks in Nautilus and Oerba #39;s schoolhouse in Final Fantasy XIII that were 13-hour clocks, and for Mog in Final Fantasy XIII-2 having a 12-hour clock to show the change in a day #39;s length. How will you spend your final days?
