The next entry of the Etrian Odyssey Untold series is essentially two games in one – the first, a Nintendo 3DS update to Etrian Odyssey 2: Heroes of Lagaard (released on Nintendo DS) with new dungeon layouts, new graphics, and system improvements from the recent Etrian Odyssey Untold . The second is the Untold portion – a brand new story mode with a fixed party, voiced dialogue, and animated cutscenes that follows the bittersweet tale of the Fafnir Knight and Princess Arianna. Like Persona Q, the Untold portion of the game has a strong focus on characters and their interactions as the story about the Fafnir Knight and Princess Arianna unfolds as they adventure forth into the ruins of Ginnungagap and the Yggdrasil Labyrinth with the hero Flavio and the two mysterious adventurers, Bertrand and Chloe.
- Creatures of Comfort - Etrian Odyssey 2 Untold has a level of refinement that could only come from seven iterations of the game. Vastly improved game systems make Etrian Odyssey 2 Untold easily approachable for beginners, but still challenging for die-hard veterans
- Brand New Additions - Etrian Odyssey 2 Untold features a brand new character class called the Fafnir. Only available in the game's Story mode, the Fafnir gives players the ability to transform into a beastly demonic form to enhance attributes and abilities - potentially turning a losing battle into a narrow victory. New changes to the Grimoire stone system let players customize their entire party as well, allowing members to use abilities from different classes
- Bring a Blanket - Just as in Etrian Odyssey Untold: The Millennium Girl and Persona Q , in addition to normal difficulty, players can choose Picnic mode for a low-difficulty experience, or the veterans amongst them can choose Expert mode for a punishing play-through
