Overview

Heroica: Castle Fortaan is a LEGO dice-rolling adventure game where 2-4 players control heroes exploring Castle Fortaan, which has fallen to the Goblin King and his monster army. Players roll a custom LEGO die to move, fight monsters, collect items, and race to reach the mission target space or defeat the monster on it. The game features modular LEGO boards that can be rearranged for different missions.
