Final Fantasy XIII (ファイナルファンタジーXIII, Fainaru Fantajī Sātīn) is a science fiction role-playing video game developed and published by Square Enix for the PlayStation 3 and Xbox 360 consoles and later for the Microsoft Windows operating system. Released in Japan in December 2009 and worldwide in March 2010, it is the thirteenth title in the mainline Final Fantasy series. The game includes fast-paced combat, a new system for the series for determining which abilities are developed for the characters called "Crystarium", and a customizable "Paradigm" system to control which abilities are used by the characters. Final Fantasy XIII includes elements from the previous games in the series, such as summoned monsters, chocobos, and airships.
The game takes place in the fictional floating world of Cocoon, whose government, the Sanctum, is ordering a purge of civilians who have supposedly come into contact with Pulse, the much-feared world below. The former soldier Lightning begins her fight against the government in order to save her sister who has been branded as an unwilling servant to a god- like being from Pulse, making her an enemy of Cocoon. Lightning is soon joined by a band of allies, and together the group also become marked by the same Pulse creature. They rally against the Sanctum while trying to discover their assigned task and whether they can avoid being turned into monsters or crystals at the completion.
Development began in 2004, and the game was first announced at Electronic Entertainment Expo (E3) 2006. Final Fantasy XIII is the flagship title of the Fabula Nova Crystallis collection of Final Fantasy games and is the first game to use Square Enix's Crystal Tools engine.
