Etrian Mystery Dungeon

Far off in the mountains, the small village Aslarga becomes a hub for
adventurers looking for fame and fortune from the Mystery Dungeons. But
dire challenges await even the most stalwart adventurers in Etrian
Mystery Dungeon, a turn-based action RPG roguelike developed by ATLUS
and Spike Chunsoft.

The Nintendo 3DS™ exclusive mixes Etrian Odyssey’s vast RPG party and
skill customization aspects, and Mystery Dungeon’s infinitely random
dungeon adventures. The action/turn based combat means that battling
monsters is not just about using the right skills, but becomes an
elegant Pas de Quatre of strategic positioning. Players form their
parties with familiar Etrian Odyssey classes, customize individuals
using Etrian-style skill trees, and then take up to four members into
the dungeons. Always randomized with various levels and paths, the
dungeons require plenty of exploration, not to mention the incredible
loot rewards -- just be wary of what waits among the deepest depths.
