Etrian Odyssey III: The Drowned City[1] is a 2010 3D dungeon crawler role-playing video game by Atlus for the Nintendo DS.

A remastered version was released for Nintendo Switch and Windows in June 2023 under the title Etrian Odyssey III HD.

These navigation icons can represent sea currents, landmarks, and footnotes of the terrain that players encountered.

Mission assignments for the player while on the sea will be to locate and reach foreign ports in order to restore Armoroad's trading roads.

However, because of the great earthquake that happened a hundred years ago, the central part of the city sank down into the bottom of the sea, along with its superior technology.

[6] The remastered version includes updated visuals and music, quality of life changes, and additional character portraits.

[8] Famitsu gave it three nines and one eight, for a total of 35 out of 40; they said that "the core charm of the series, with its Wizardry-style gameplay and player-built maps, is as strong as ever".
