About Killer Depths

Killer Depths is a submarine horror game. Study the monsters that lurk below and adjust the settings on your vessel according to what you think is currently stalking you. 

FEATURES 

  • Over a dozen different creatures haunt the waters. Many can not be seen or heard, requiring more intuitive investigation.

  • The brightness, noise and the speed of the vessel will attract or scare off monsters.

  • Monster attacks can cause flooding, power outages and explosions. Use tools to keep the vessel from imploding.

  • Vigilant divers may uncover encrypted messages revealing details about the world and their employer.

  • What you see and hear may not be real.

GAMEPLAY

You are the lone crew member of a submarine tasked with retrieving cargo that has landed on the ocean floor.  Each day you will be given an updated bestiary of potential threats in the water and all known information on how to avoid them. Keep the lights on and windows open to spot predators swimming around; then again, you may need to turn the lights off and keep the windows closed to pass by creatures that relay on sight.

The submarine's CO2 Scrubber is the only thing providing you with breathable air, but you may need to shut it down to lower your noise levels, just don't forget to turn it back on. Photography, Thermal Vision, a Radio Headset and Sonar are some of the many tools scattered around the submarine you will use to detect what might be out there.

Anger a monster and it will attack, causing heavy damage, system malfunctions, fires, water leaks and other issues you will need to fix, all while figuring out what could have attacked you. Retrieve the target without crashing into the sea floor, and try not to die on your way back to the surface.
