Etrian Odyssey (JP) is the first installment in the Etrian Odyssey series. It is a first-person, dungeon exploration, role-playing game developed by Atlus and Lancarse and published by Atlus (except in Europe, where it was published by Nintendo). The game has been remade for the 3DS as Etrian Odyssey Untold: The Millennium Girl with a proper story and several conventions added by later entries.


The game contains various RPG elements such as random battles, leveling up, and a host of things to find and collect. However, Etrian Odyssey is unique in the fact that as you explore the labyrinth, you can create a map of each floor yourself using the stylus and the bottom screen of the Nintendo DS, similar to older games such as Wizardry, where players often created their own maps of the dungeon on graph paper.

The player goes through 25 floors of the labyrinth, with over 70 optional quests that can be completed, as well as an additional 5 floors which contain many of the game's most challenging enemies and are the most difficult floors to map.

The game groups the floors into different sections, each referred to as a stratum, which all contain unique monsters and appearances. The game is known to be challenging, requiring the player to plan ahead, and create a well balanced team capable of facing a number of different situations.

The title was first announced by Atlus through Famitsu after demonstrating it behind closed doors at E3 2006.

The development team within Atlus was led by Kazuya Niinou who also directed the development of Atlus' first in-house game for the DSTrauma Center: Under the Knife. The game features character designs by Yuji Himukai, monster design by Shin Nagasawa, a story by Shigeo Komori, and FM-like music by Yuzo Koshiro.

The game was originally to be released internationally as Yggdrasil Labyrinth, but was renamed to avoid any possible confusion with Yggdra Union (a game published in North America by Atlus a year earlier) or Deep Labyrinth.


The game received "favorable" reviews with a 75 according to Metacritic. Although the title was recognized as a very solid classically inspired RPG, it was noted that this greatly limits its appeal to a certain "hardcore" demographic especially with its difficulty
