PIECES OF THE DEEP 〜海底遺産回収録 〜

Run through the depths.
Recover the relics of a lost civilization.

PIECES OF THE DEEP is a roguelite action game built around auto-running exploration, where split-second decisions determine survival.

You play as Nyarmar, a small creature who lost its home in a massive seabed quake.
Rescued by a team of surface-dwelling explorers, you repay their kindness by helping with dangerous deep-sea expeditions.

■ Procedurally Generated Dungeons × Instant Decisions

Each dungeon is procedurally generated.
Your character runs forward automatically—your role is to dodge hazards, defeat enemies, and choose branching paths while pushing toward the depths.

Simple controls, demanding judgment.
Every moment matters.

■ Recover Relics and Expand Your Base

At the end of each dungeon awaits a powerful boss.
Defeat it to obtain relics left behind by an ancient civilization—materials and incomplete blueprints scattered across the seabed.

Back at base, recovered relics are analyzed and used to restore advanced technology,
unlocking new capabilities for even deeper dives.

Explore. Recover. Grow stronger. Dive again.

■ A Story from the One Who Retrieves

You are not the one who deciphers the past.
You are the one who descends—again and again—to bring something back.

This is not the story of a hero who saves the world,
but a record of those who recover what was lost.
