A card game based on Avalon Hill's Atlantic Storm in which players explore a Haunted House. Each turn players can either play an explorer card (and appropriate items) or a monster card (and appropriate items). This creates two teams: explorers vs. monsters. Whichever side has the most points in the chosen combat category wins. After each victory, the spoils (room card and cards from the losing side) are divided up among the winners. The player who has the most hourglass symbols on the cards they win wins the game. - BoardGameGeek
