Final Fantasy XIII-2 is the sequel to Final Fantasy XIII developed by Square Enix for the PlayStation 3 and Xbox 360, and later released to Microsoft Windows PCs via Steam. It is a part of the Fabula Nova Crystallis series and does not have the lighthearted tone of Final Fantasy X-2. Note that the release of Final Fantasy XIII-2 outside Japan does not include Japanese interface or subtitles support.
In the E3 2011 trailer, two other playable characters were shown: Serah, Lightning's sister and an NPC in the first game, and a young man named Noel. The paradigm system from Final Fantasy XIII was also shown.
