Very fun dice based area control, and it’s asymmetrical, so players have different goals / ways to play, here’s a description from bgg

One player controls the Bluefin Squadron, a company of sharks and their toothy friends, who patrol these waters and keep order with shot and sword. Another player controls the Mollusk Union, an alliance of undersea creatures and their comrades-in-arms, who fight to reclaim their ancestral home. In games with more people, some players control Smugglers, maverick captains who run blockades to smuggle luxuries and essentials, delivering them to those with the most need—or the most coin. Explore the seas. As you play, you’ll make a unique map full of treasure troves, dangerous wreckage, and mighty sea currents, using deluxe double-layer region tiles.
