Echoes of Eta

Welcome to Nereid-42

Play as Viktor Revik, who wakes up after the planetary apocalypse. 

Join the deep-sea survival journey set on the mysterious 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.
Underwater Survival Journey

Balance your survival needs for oxygen, hunger, and thirst in an extreme alien environment. Explore diverse locations to scavenge resources and uncover potential technologies that can enhance your survival capabilities.

Your Ship, Your Mobile Base
Your ship comes equipped with automation systems and extensive customisation options. However, the harsh underwater environment of Nereid-42 will constantly challenge your ability to survive.

Use available space to construct modular structures that support your long-term survival. Manage production resources and monitor your ship's power supply before venturing into the deep sea.

Craft Advanced Tools

Create survival equipment and deployable modules to upgrade your character. From repair tools to automated defence turrets, every tool can become essential for survival.

Progress technology

Advance through Eta's self-evolving technology system. Analyse unknown entities and collect data from the remnants of humanity's lost civilisation. Progress the tech tree and unlock new craftable structures and equipment blueprints.

Combat Hostile Threats

P.U.L.S.E. provides comprehensive solutions for defence and offence by analysing local extreme threats and recovered human weapon technologies. Construct advanced biomechanical robots to accompany you on your journey, protect mining operations, and fight against hostile predators lurking in the abyss.

Gather Rare Resources

Use moonpool robotic arms and automated mechanical units to recover valuable materials, or explore the ocean depths yourself in a specialised diving suit to discover rare resources hidden beneath the surface.

Biomechanical Companions
Research and replicate the unique characteristics of local species to create advanced biomechanical companions. They can assist you with transportation, provide powerful combat capabilities, or extract valuable resources.

Upgrade and customise your companions through equipment and module slot systems, enhancing their abilities as you explore the unknown world together.
