You wake up to the sound of waves crashing against steel.

Cold concrete presses against your skin. Rusted bars loom overhead. Beyond the narrow slit of your cell window, there is nothing but endless ocean — black, violent, and impossibly far from salvation.

You don’t remember how you got here.

The Forgotten’s Vault is a first-person survival horror experience set inside a decaying prison isolated in the middle of the sea. Every corridor is suffocating. Every flickering light hides movement. Every door you unlock brings you closer to freedom… or something far worse.

Explore claustrophobic cell blocks, flooded maintenance tunnels, interrogation rooms, and forgotten execution chambers. Search for hidden keys and crucial objects buried within the prison’s rotting architecture. Solve environmental puzzles that force you deeper into the facility’s heart — where the air feels heavier, and the silence feels alive.

But you are not alone.

Multiple horrifying entities roam the prison. They hear you. They learn your routes. They hunt without mercy. There is no combat. No weapons. No last stand.

Only stealth.
Only running.
Only hiding in the dark and praying they don’t open the locker.

The ocean isolates you.
The prison traps you.
The monsters stalk you.

Your only goal is simple: Survive. Escape. Don’t become another forgotten soul.
