Project Thalasmophobia

Build a safe mainland base with the Create Mod, but beware: the shores drop instantly into a flat, pitch-black $Y = -40$ abyss. Build submarines, turn on your headlights, and brace yourself for whatever is hunting in the dark.

Project Thalassophobia

The Premise

On the surface, the world seems normal. Massive continents, sweeping mountain ranges, and rich land plains give you a safe place to build, mine, and establish your footing. But the safety of the shore is an illusion.

The shores of these vast continents drop off instantly into a flat, midnight-blue $Y = -40$ abyssal void that wraps around the entire globe. The mainland offers security, but the true progression, rare treasures, and dark secrets are buried deep beneath the waves. You can only stay on land for so long before the deep calls you down.


Key Features

  • 🏔️ Continental Strongholds: Explore a massive landmass generated by Tectonic. Build a safe homestead, secure your resources, and establish a rock-solid footing on ground before facing the terrors of the open sea.

  • ⚙️ Industrial Submarines: Advance through the mechanical tech tree of the Create Mod to engineer fully functional custom submarines. Design iron hulls, automated propellers, and deep-sea diving vessels capable of surviving the pressure.

  • 🌫️ The Suffocating Dark: Experience true atmospheric horror. As your submarine leaves the continental shelf and plunges into the oceanic valleys, the sunlight completely fades into a heavy, oppressive ink-black fog. You will be completely blind without your headlights.

  • 🛑 The Unknown Abyss: You are absolutely not alone in the dark. Deep within the massive ocean trenches, colossal, ancient forces shadow your every move. They are fast, aggressive, and hunting just beyond the reach of your headlights.
