It is a turn-based strategy game featuring kingdom exploration, resource management, town development, hero progression, and tactical grid-based combat. Players explore a fantasy world, recruit armies, collect artifacts, and develop their heroes while commanding one of nine factions. The game combines the original campaigns into a unified narrative and includes online multiplayer for up to eight players, local Hot Seat mode, and an editor for creating maps and campaigns.
Queen Catherine leads a campaign to restore order to Erathia, a kingdom thrown into turmoil following her father's assassination and the invasion of hostile factions. The story brings together the original Heroes of Might and Magic III campaigns and those from its two expansions, Armageddon's Blade and The Shadow of Death, into a continuous narrative, with an additional introductory prologue.
