Risk the Abyss is a 2-4 player dice game in which players compete to become the greatest Deep Sea Diver. Players take turns by rolling dice with a Yahtzee-style mechanism, and then executing the actions from the resulting dice. Each die face represents a different action that a player can take: Flippers and Anchors are used to move the Divers around the Ocean Grid. Harpoons and Keys are used to acquire Sea Creature and Treasure cards. Oxygen is used to hang onto face up cards. Radios are used to return to the Boat and bank cards. Players must strategically collect sets of cards to gain the most points by the end of the game. —description from the designer
