If you have heard of Subnautica, what do you think of it? It's a survival game similar to stranded deep, but you're set on an alien planet that is made up of only water and of course, the seafloor. Your ship, the Aurora, has crashed on this planet and you are the only survivor of your entire crew, you must get resources and make seabases. Here are some of what I mentioned, oh, and some creatures, too.
