July, 1961.

Beneath the freezing waters of the Cold War, the Soviet nuclear ballistic-missile submarine K-47 Volkodav begins a classified deployment into the North Atlantic.

136 men go aboard.

Whether 136 come home is up to what happens beneath the surface.

BLACK DEPTH is a high-stakes, strategy-driven submarine survival-horror RPG set during the early nuclear age. Take command of the Volkodav—or enter her crew as an engineer, reactor technician, doctor, sonar operator, political officer, damage-control specialist, enlisted sailor, or a character entirely your own.

Manage failing machinery. Make impossible decisions. Navigate Soviet command, NATO forces, radiation, fire, flooding, exhaustion, limited resources, conflicting orders, and a submarine that may be far less reliable than Moscow believes.

There is no predetermined disaster.

There is no predetermined ending.

Your decisions shape which problems are discovered, which become catastrophes, who survives, whether the mission succeeds, and whether K-47 ever sees home again.

The ocean can crush you.
The reactor can poison you.
Moscow can condemn you.

Choose carefully.

⚠ DEAD DOVE / MATURE HISTORICAL-FICTION HORROR
Potential themes include death, serious injury, burns, radiation sickness, drowning, blood, medical trauma, claustrophobia, psychological distress, military coercion, nuclear themes, moral dilemmas, and Cold War political tension.

K-47 Volkodav, Operation Winter Wolf, and the central cast and storyline of BLACK DEPTH are fictional. The RPG draws inspiration from the technological dangers and historical atmosphere of early Cold War submarine service but is not a reenactment of a specific real-world submarine disaster.
