ABOUT THE GAME

Experience the deep sea through exploration, combat, and random events. Manage scarce resources, face abyssal threats, and uncover the mystery behind humanity’s collapse.

GALLERY

Moonpool

Moonpool room is one of the essential rooms on the ship. It allows you to extract and collect resources from the world.

The world is not as it appears to be

STORY & LORE

Play as Viktor Revik, wake up after the planetary apocalypse.

Join the deep-sea survival journey set on the alien ocean planet Nereid-42. Discover what happened to existing human colonies after the Crimson Cataclysm, and the secrets that are hidden under the deep sea.

FULL GAME PLANNED FEATURES

Take direct control of the extremely advanced ETA ship at the very start.

Travel to various underwater locations in 3D maps to find resources, random events, study anomalies, and develop new technologies.

Your survival depends on your decisions.

(The underwater travel is currently being developed, this concept image’s background belongs to artist Jeff Christy.

The purpose of this image only serves as an early stage idea reference and will be replaced with 3D environment later)

Mining Spot

Collect resources from the rich area. Perform manual setup in the deep ocean before using the Moonpool claw to retrieve resources for refinement.

Survey point

Place to rest and prepare. Stay on the spot and wait for the ship to complete scanning, which guarantees a positive event upon completion.

Unknown Habitation

Raid abandoned or active habitations to collect new blueprints and rare resources. Prepare for combat action.

More

Follow the development news for more about the point of interest.

Instead of grinding resources with manual labour, your ship comes prepared with automation and advanced tools.

However, the harsh underwater environment on Nereid-42 will always present itself as a challenge. Mine under the deep sea, and try not to disturb something unfriendly.

Your ship is the core of your survival. Repair damaged parts, balance power and resources, or experience intense horror in the dark.
