"At 800 meters deep, the weight of the ocean isn't the only thing crushing you." Four saturation divers are trapped in a steel coffin at the bottom of the North Sea. Their mission: a routine repair on an ultra-deep pipeline. But in the crushing darkness of the abyssal plain, they uncover an obsidian structure that was never meant to be disturbed. As a haunting resonance begins to bleed through the habitat's walls, the crew's sanity fractures. Breathing a volatile mix of gases that distorts their voices and their minds, they realize the structure is waking up. Outside, the pressure is lethal. Inside, a violent psychosis is turning friends into butchers. In an environment where the air itself is a poison and every bolt is screaming under the weight of the sea, survival is a pipe dream. The pressure is rising. The blood is boiling. And the abyss is tired of watching. A brutal, claustrophobic descent into industrial horror where the deep doesn't just take your life-it erases your humanity.
