Conan is an asymmetric dungeon-crawl game where heroes work together to complete scenario-specific objectives, while one player controls the Overlord and its monsters. Players assign and recover energy gems to move, attack, defend, manipulate objects, and reroll dice. The heroes win by fulfilling specific scenario conditions, such as rescuing a princess or defeating a specific enemy; the Overlord wins if the heroes fail to meet their objectives or all heroes die.
