​About Etrian Odyssey V: Beyond the Myth
​Genre: First-Person Dungeon Crawler RPG.
​Platform: Nintendo 3DS.
​Developer/Publisher: Atlus.
​Key Features:
​Cartography: The signature feature of the series is using the 3DS stylus and lower screen to manually draw a map as you explore the massive, multi-layered dungeons (the Yggdrasil Labyrinth).
​Customization: The game revolves around creating your own guild of adventurers from four unique races and ten classes, with deep skill trees and subclassing options for highly strategic party building.
​High Difficulty: The series is known for its challenging, turn-based combat, especially against the powerful mini-bosses known as FOEs (Formido Oppugnatura Exsequens), which often roam the map and must be avoided or outsmarted until your party is strong enough.
