This E3 has been filled with many announcements of must-play games and Fire Emblem Warriors is one of them.
Nintendo told fans through a Direct video in January that the Fire Emblem Warriors game was in production. At their E3 presentation, a new story trailer was shown giving us a few details about the new title. A kingdom that has not appeared in previous Fire Emblem games serves as the setting. Within the small country, two siblings rise to save their people as an evil dragon moves in to swallow the people. Heroes from the other realms of the FE universe will also be making appearances. By working together these characters will be able to bring back the light to the world.
Corrin (female version), Prince Xander (Nohr Kingdom), and Prince Ryoma (Hoshido) are all from the FE Fates games and are found within the trailer. The video features mostly the sword-type characters, yet we can hope that magical-type characters will also be included in the roster. Maybe Nintendo is waiting to reveal the full list of characters until the summer.
FE Warriors will be released on the Nintendo Switch, 3DS, and 2Ds in Fall 2017.
