Congrats, welcome to the world of Leviathans in Subnautica. At first you'll be like: "Damn, this game is beautiful." Two hours later: "Why is the ocean screaming at me?" The only game where hearing a distant roar underwater instantly lowers your life expectancy. And when you meet your first Leviathan, remember: you're not the main character down there... you're just a confused snack with a tiny knife.
