Communication with the surface is cut off. You can't even call for help.
About
Uncovering the Mysteries of the Deep
With that ambition, five elite crew members boarded a state-of-the-art submarine modified to withstand any pressure.
At first, everything went smoothly, and everyone expected to return without incident.
However...
The Present
The submarine carrying the five souls drifts through the dark sea at a depth of 10,000 meters, far beyond the reach of sunlight.
Unexpectedly, after crossing the 10,000-meter mark, communication with the surface was severed, making it impossible to confirm their location. Furthermore, due to an unexplained engine failure, an immediate ascent to the surface is no longer possible.
Occasionally, caught in the light leaking from the submarine's windows, mysterious shadows appear. They continue to wear down the crew's mental state even now.

--- A few days later
Damn it...
He slams his hand onto the console where the radio sits. It seems they really have lost all contact with the surface.
...So, what do we do now?
He scratches his head aggressively.
