Subtitled A Realm Reborn, the enhanced version of Square's massively multiplayer online role-playing game is due to launch in beta form later this year.
The trailer delves into the history of the Garlean Empire's invasion and the subsequent fate of the surviving adventurers.
The original Final Fantasy XIV was plagued by frequent bugs, lag, and numerous other issues following its launch.
Square Enix has released multiple patches to fix the issues, but remained unhappy with the game, saying that it had hurt the brand.
The firm subsequently decided to release the 2.0 update for the game to overhaul its graphics, servers and various other aspects.
