How to create good looking water like stranded deep?

If anyone could help me with this issue that would be great. I’m new to Unity and i’ve been wondering if anyone could tell me how to make good looking water, more specifically the water used in the new Stranded Deep game. Any one know how they did it? any help would be awesome!

I’m also curious… we’ve checked all available plugins for water and still cannot find anything like this. The closest match is Smart Water 3D, however it’s not so pretty as in this game.
