Uncover the truth behind the labyrinth that swallows all. By choosing first to immerse yourself in Story mode, you will encounter the maiden who has lived a thousand years and the growing mystery that surrounds her past—a past that may affect the present and future of Etria.

Should you brave Classic mode, you will experience the beautifully upgraded version of the original Etrian Odyssey adventure, with new 3D graphics and gameplay improvements as seen in Etrian Odyssey IV, as well as a fully orchestrated BGM to accompany your journey. Scour through the dungeon's many layers and fend off the unknown to discover the truth behind the Yggdrasil Tree.

Choosing either mode will unravel the engrossing tale that signaled the start of the grand Etrian Odyssey series. How will the newest generation of explorers fare in unearthing Etria's latest tale?
