Submarine Escape

BACKGROUND
In the pitch-black ocean depths, deep within an exploration submarine, the protagonist falls into a deep slumber, afflicted by a mysterious high fever—unaware of the blaring alarms and desperate screams echoing through the vessel.
Waking up late, he opens the door only to find narrow corridors stained with gruesome trails of blood, with no sign of the other crew members. As he searches the submarine while avoiding unidentified sounds echoing from the dark, the sonar screen catches the signal of a rescue submarine—a single ray of hope.
However, relief is short-lived as he realizes another unknown threat is slowly creeping toward him at the edge of the sonar screen...

THREATS LURKING INSIDE THE SUBMARINE

Survive the monster that slaughtered everyone except you.
When an alarm sounds, the creature goes berserk, destroying doors to annihilate the source of the noise. You must get away from that area immediately.
...Somewhere in the submarine, the forgotten truth about the monster may be recorded.

RESEARCH THE MUTATION CURE

Gather clues from the deep-sea creature database monitor and combine the right samples to craft a cure. If you do not take the cure in time, you will turn into a complete monster and sink into the abyss along with the submarine.

FIRE TORPEDOES TO REPEL DEEP-SEA MONSTERS

Eerie sounds echo from the depths of the ocean. Launch torpedoes to stop the creature before it rams into the submarine.

EVADE THE MONSTER AND RISE TO THE SURFACE

Though weakened by the torpedo, the monster still hungers for your life. Dodge its attacks with precise timing. Never drop your guard until you escape the abyss and behold the blue light above.
