Huge Ocean

You are alone submarine pilot descending into the huge ocean,
a 20,000 meter vertical journey through crushing pressure,
total darkness, and creatures that have never seen the light.
From the sunlit Epipelagic zone to the nightmare trenches of the Hadal,
every meter brings new danger, new beauty,
and new horrors.
