Captain your fishing trawler to explore a collection of remote isles, and their surrounding depths, to see what lies below. Sell your catch to the locals and complete quests to learn more about each area's troubled past. Outfit your boat with better equipment to trawl deep-sea trenches and navigate to far-off lands, but keep an eye on the time. You might not like what finds you in the dark... Starting from your new home in the remote archipelago, ‘The Marrows', take to the water and scour the depths for curious collectables and over 125 deep sea denizens. Explore each area while completing quests and visiting neighbouring island regions – each with their own unique opportunities, inhabitants, and secrets.
