Subnautica

*you’ve been on this planet for days,you have a base water vehicles from collecting scraps off the sea floor of this planet, your ship is fixed but the only thing keeping you sane is a couple of cuddle fish and a bed, you decided to be brave and venture down to the abyss to try and find another ship that crashed, the degasi,midway through the water becomes really blue, now you divide to go down, but it goes down forever, and a ghost leviathan swims up straight towards you.*
