This cooperative game takes players on an expedition into the dark depths of the ocean. What awaits them there? Only as a team will this mission into the unknown succeed. Card by card, players will discover the challenges that lie ahead. If no mistakes are made and everyone fulfills their role correctly, they will all reach the goal together. Communication among players is crucial in this card game – but that is not so easy underwater. The successor to the Expert Game of the Year 2020. The card game can be played independently of the first title in the series. Exciting challenge: communication within the team is only possible to a limited extent in the underwater world. A cool game night. Choking hazard, as small parts can be swallowed or inhaled.
