Fire Emblem: Hero of Light and Shadow is a remake of half of the classic Super Nintendo game Fire Emblem: Monshō no Nazo. The remake is of Book 2 of the original game. The game stars Marth in the War of Heroes. The player takes the role of Marth’s close ally known as the “Hero of Shadow”, although they control all characters on the field that are in their force. The game plays similarly to other recent Fire Emblem titles, with the player choosing the actions of each unit on their turn. Light and Shadow includes four difficulty levels as well as a Casual Mode that makes unit deaths non-permanent in the campaign. The standard mode is still available for players (death is permanent for units).
The game also includes the orginal four part BS Fire Emblem Akaneia Senki Super Famicom Sattelaview series in the Extras.
