About the Game

Set adrift in a vast and uncaring ocean, you find a decrepit submarine, seemingly abandoned and in disrepair. Determined to make your way back to civilization, you must maintain the submarine and keep yourself alive.

SUBMARINE

The derelict submarine you find yourself in is your only lifeline. The various systems onboard are critical to navigating the abyssal waters but start in disrepair. Utilize them to find your way back to civilization; use the sonar to see your surroundings, the navigation console to chart out your route, and the submarine turrets to defend the submarine. Keep the sub afloat through careful maintenance lest you sink to the depths below.


SURVIVAL

You are a fragile being in an unkind world. Gather food, scavenge for supplies, and find equipment to keep yourself alive for another day. Store your goods in your hermetic trunk until you can get them back to your submarine.


THE OCEAN

The ocean is uncaring and beautiful. Isolated in its depths, you are left to make your way through regions of flooded ruins, now inhabited by an active ecosystem of unfamiliar sea creatures and overgrown flora. You are out of your element and surrounded by potential threats, exercise caution and use violence as a last resort.
