The gameplay of Fire Emblem Shadows combines real-time strategy and social deduction. One of the three allies participating in each battle is secretly a treacherous disciple of shadow. Players choose to take on the role of either a disciple of light, aiming to find their way through the labyrinth, or a disciple of shadow. After the initial battle, players vote to determine who they believe is the treacherous disciple of shadow. The outcome of the vote affects whether the next battle is more favorable or more challenging. Whether the disciples of light can correctly discover the traitor—or the disciple of shadow can successfully deceive the others—holds the key to how the next battle unfolds.
