Nautilus*

Players build an underwater research station while trying to find Atlantis, recover sunken treasures, and gather resources. The gameboard depicts the ocean floor as a grid with shades indicating depth levels.

Each round consists of three phases: expanding the station with new research facilities that offer benefits based on their type, deploying scientists at a cost to utilize these facilities, and exploring with up to three submarines to search for treasures and remnants of Atlantis. Points are awarded for recovered Atlantis chips and discoveries, with bonuses for meeting special objectives. The game concludes when certain conditions regarding Atlantis chips, station expansions, or marine discoveries are met.
