Quietly revealed late last month, Bravely Default: For the Sequel is an enhanced version of the original game with support for Japanese, English, French, Italian, German, and Spanish language options.
According to Siliconera, the game also features enhanced battle mechanics which have been influenced by those being created for the proper Bravely Default sequel.
Additionally, battle speed is reportedly a little quicker, and the game offers players the option to speed up attack effects as well as an Auto Battle function that is designed to streamline grinding.
An event viewer has also been added to Bravely Default: For the Sequel, along with a tweaked user interface that gives players more information on equipment and classes.
Developed by Silicon Studio, Bravely Default is a JRPG that uses a turn-based battle system seen in Square Enix's Final Fantasy titles, and also includes augmented reality features that utilise the 3DS camera.
Nintendo has confirmed that Bravely Default will be released in Europe this year.
