The reveal trailer for Fortune’s Weave introduced the upcoming title, which is expected to include factional rivalries reminiscent of earlier entries in the Fire Emblem series, such as Fates, Awakening, and Three Houses. The game will introduce entirely new characters set within a fresh environment, which some believe may be more engaging than what was presented in Fire Emblem Engage.
Central to the game’s narrative is the Heroic Games, a gladiator-style competition anticipated to significantly affect the overarching story. Fortune’s Weave maintains the series’ tactical RPG gameplay, characterized by its rock-paper-scissors combat mechanics. This installment is set to introduce new combat units with elements inspired by gladiatorial themes. More details about Fire Emblem: Fortune’s Weave are expected to emerge as its release on the Switch 2 approaches next year.
