The story focuses on the prince of the Kingdom of Iris and his companions as they struggle during a turbulent era. Players are said to be able to combine the might of nearby allies to enter dual battles to defeat enemies. Gameplay footage shows that the traversable world map, last seen in Fire Emblem: The Sacred Stones, and special skills like Astra from Fire Emblem: Radiant Dawn will make a return. This game will feature a player character that can be customized, a feature last seen in Fire Emblem: Shin Monsho no Nazo ~Hikari to Kage no Eiyu~. Just like in the previous game the player can choose classic mode and casual mode.
