About the Game

You're trapped in an old Cold War submarine. Your only goal: survive. Complete urgent repairs, manage limited resources, and keep the systems running. You can’t see each other. One misstep, one wrong call, and it’s all over.


Use your voice. Trust your partner. And don't run out of time.

You’ll never make it alone. Communicate through a crackling walkie-talkie. One speaks, the other listens - no exceptions. Relay codes, fix malfunctions, and guide each other through a maze of rust, steam, and shadows.

Forget clear sight. All you’ve got is each other’s voice. Keep it steady.

Time is not your friend. Each second wasted brings your doom closer - flooding compartments, failing engines, failing minds. Complete your tasks quickly. Stay calm under pressure. And if you mess up?

You’ll hear it. Feel it. Maybe even see it... before the ocean swallows you whole.
