The expansion Heroes of Might & Magic III: The Board Game – Naval Battles offers a new dimension to the game world, allowing players to explore dangerous seas around Antagarich. Here, players battle for hidden treasures, face frightening creatures, and experience naval combat through three new scenarios suitable for solo, cooperative, and battle modes.

The expansion introduces Creature Banks with preset defenders and rewards that increase depending on the difficulty of the fight. The Empowered Ability cards provide stronger versions of familiar abilities, while the double-sided neoprene maps support both naval and land battles. The included single-player scenario is the first that can be played outside a regular campaign.

The package includes a missions book, two double-sided neoprene battle boards, 82 cards, 43 counters, and four attack dice. This expansion requires the core version of the game Heroes of Might & Magic III: The Board Game.
