The short video above was released by Atlus today via its Japanese Youtube account, though fans have correctly identified the game announcement as Etrian Odyssey V.
You won't find more than a fans logo sequence and a shot of the world, though it looks decidedly vibrant and far reaching. We have little else to go on, though Atlus does provide a home page for the title. We'll watch the site for more and continue our coverage of Atlus games with Persona Q: Shadow of the Labyrinth, out this week.
