What is the title of the mobile Fire Emblem game released in 2017?

The mobile Fire Emblem game released in 2017 is Fire Emblem Heroes. It is a free-to-play tactical role-playing game developed by Intelligent Systems and published by Nintendo for Android and iOS devices.

Heroes is a crossover celebration of the series rather than a retelling of one console game. Players summon, train, and deploy characters from many Fire Emblem titles, alongside original heroes and villains from the game’s own story. Battles use compact maps designed for mobile play, with teams of four units and familiar weapon, class, skill, and support systems.

The game launched on February 2, 2017, following a Nintendo announcement and a promotional “Choose Your Legends” popularity vote. It is often confused with Fire Emblem Warriors, a console action game released later in 2017, or Fire Emblem Echoes: Shadows of Valentia, a Nintendo 3DS title. Heroes is the series’ dedicated mobile spin-off.
