Now out in North America, Square Enix’s new fighter Dissidia Duodecim: Final Fantasy already has a lot of updates available, with a few more to come in the next month.
The DLC breakdown looks like this:
Now available: Aerith, via code from a purchase of the story prologue, Dissidia Duodecim Prologus: Final Fantasy; an alternate costume for Tifa, through an Amazon pre-order code; Cloud’s Kingdom Hearts garb, via GameStop pre-order code.
Also available “now” is Lightning’s Aya Brea lookalike outfit, but since it comes via a packed-in code with The Third Birthday, players can’t actually obtain this outfit until the 29th when that game ships.
On March 29, a “Nameless Warrior” costume for the Warrior of Light will be available as a free download on the PSN Store. When Final Fantasy IV: The Complete Collection is released in April, Cecil will get a “Knight of Two Moons” costume by way of a voucher code.
