The upcoming sequel to Final Fantasy XIII will feature time travel as both a storyline and gameplay mechanic. On the gameplay front, locations in the game feature time gates that transport Serah and Noel into different time periods. An area that is full of life in one time period is a ruined wreck in another. These alternate time periods feature artifacts to uncover.
On the storyline front, Noel Kreiss, one of the two leads in FFXIII-2, is from a ruined future where he is the sole survivor. He travels back to the present time to fix the future. Serah, the other lead, is travelling to find her sister, Lightning. FFXIII-2 is currently set for an end of year release in Japan and early 2012 in North America and Europe.
