According to a press release from Atlus this morning, Etrian Odyssey 2 Untold: The Fafnir Knight is coming out this summer.
The Etrian Odyssey series is a hardcore-slanted dungeon crawler where you assemble a team of create a characters and well, dungeon crawl. Similar to the Class of Heroes or Wizardy games, the enemies are tough and it takes a lot of careful planning and grinding to make your way through the game.
The Untold series also features a story mode that helps introduce the various aspects of the genre in addition to the near-storyless excursion into the dungeon depths. I haven't played the first myself, and I'm not really a fan of these types of games, but the missus really likes them (she grew up playing the old Wizardry games on PC).
However, the new character, the titular Fafnir Knight can transform. I do really like characters with that ability, so it's a shame that he's only in the story mode. I'd really prefer that to be a class than some of the ones I wouldn't use.
If you are interested, you can watch the announcement trailer here. The game will launch in the summer at $49.99 on the Nintendo 3DS system family.
