Etrian Odyssey 3: The Drowned City was the first game in the series that radically redesigned how the game was played. Instead of a typical Stratum including five floors, it now included only four - which also reduces the depth of the Labyrinth itself as compared with other games.
Perhaps the most radical change to the game, however, was an added game feature. In addition to the tradition town and labyrinth set up, at a point in the game players gain ownership of a ship that they are then able to take out sailing on the sea. The ship and sea world act similar in some ways to its own labyrinth with various different rules on the abilities to move and the activities that can be performed. Like the labyrinth, there are FOEs and monsters to fight.
Not only is there a storyline even more complex than that of the Etrian Odyssey 2, but the game opens up a New Game+ when it has been beaten so that the player can attempt to travel another story branch of the game.
