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.

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 the alien ocean planet, and develop new technologies.

Your survival depends on your decisions.

Mining

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

Underwater Survey

Conduct comprehensive area scanning to uncover what's hidden in various points of interest.

Creature hive

Decide if you want to take extra risk by harvesting creature hideouts, in favour of resource gain.

Abandoned habitation

Search through various abandoned facilities. Beware the military or security bots that are guarding the secrets long after humanity‘s collapse.

And more

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.

P.U.L.S.E. is your ship's beating heart and your new assistant.

With the help of its self-evolving technology, P.U.L.S.E. can use collected data to upgrade itself and your equipment. You will be able to customise equipment, ship, and even robotic allies to help you survive longer.

Upgrade and unlock. Collect valuable alien organic or artificial samples. Study them and unlock new technologies with the help of Eta ship's self-evolving technology.

Robotic Manufacture

Build robotic units and send them out to the underwater world. They can repair the ship, find and collect resources, aid you in combat, and much more.
