In the demo, Lighting is tracking down Snow Villiers in the city of Yusnaan and must "fight through the chaos to see what happened."
Equipment sets are now called Schemas, replacing the paradigms accustomed to Final Fantasy XIII and XIII-2, the defaults are The Savior, Dark Muse and Black Mage. More Schemas will unlock as your progress through the demo, including familiar sets like Dragoon, Red Made and Heart Stealer.
"Once in battle, you’ll notice how the battle system has evolved from the traditional paradigm shift party system into strategically using Schema," Mat Kishimoto, associate product manager at Square Enix wrote in a post on the PlayStation blog. "Each Schema has its own ATB gauge, allowing you to attack relentlessly with commands mapped to corresponding buttons. Then you’ll switch to a new Schema, and all of your attacks change too, allowing you to pummel the enemy with different elements and attacks. Lightning is a one-woman army."
Additionally, the demo gives you a taste of a newly introduced feature called Outerworld, which is a way for players to connect via social networks like Facebook and Twitter. In the demo you will be allowed to post your battle scores online, however, the main game will further the Outerworld experience by allowing you to buy and sell your items from and to your friends.
Another piece of DLC -- Final Fantasy VI's Siegfried garb -- will unlock for those who beat the boss battle at the end of the demo and post their score online via Outerworld.
These in-game costumes are not available to use in the demo but will be carried over to the main game.
If that wasn't enough, Square Enix is also offering the Guardian Corps and Etro's Guardian garbs to players with save data from Final Fantasy XIII and/or Final Fantasy XIII-2.
Lighting Returns: Final Fantasy XIII releases on February 11, 2014 for PlayStation 3 and Xbox 360, pre-orders have already begun. Oh yeah, you'll also receive Cloud Strife's Solder 1st Class Uniform just for pre-ordering the game.
