Fire Emblem, like all the other games in the series, is a turn-based strategy RPG in which players move characters around a grid, much like a chessboard, in order to complete a certain predefined objective like capturing an enemy base or surviving a certain amount of turns. The single-player campaign is divided into chapters which generally begin with story elements presented through the use of scenes animated with cut-outs of the main characters, then followed by a battle with an enemy. More cutscenes and a chance to save follow the conclusion of the battle.
The battle system operates under principles that most of the Fire Emblem games follow, in that a sword has the advantage over an axe, an axe has the advantage over a lance, and a lance has the advantage over the sword (known as the “weapon triangle”). The bow in the game isn’t a part of any weapon triangle, but is specially effective against flying units. Similarly, the magic system is also structured through a triangle, the Trinity of Magic, in that dark magic possess an advantage over anima magic, anima over light magic and light magic over dark magic.
As with all Fire Emblem games, if a unit falls in battle, he or she can never be used again. However, an exception is made for characters in Lyn’s tale, who will be reborn in Eliwood’s tale even if they are defeated during Lyn’s tale.
