This upcoming expansion for Barotrauma introduces significant new elements to the submarine simulation experience. It focuses on expanding player agency and introducing new challenges within the hostile environment of Europa. The expansion requires the base game to play and aims to provide a substantial addition to the existing gameplay loop.

What is this expansion?

This expansion is designed to enhance the core Barotrauma experience. It builds upon the established gameplay of managing submarines and surviving the depths of Europa by introducing new systems and a mysterious new threat.

Outpost Ownership and Management

A central new feature is the ability for players to own and manage outposts. This introduces a strategic layer where players can establish, build, and maintain their own bases on Europa. This system allows for greater control over player operations and provides a persistent element to the game world.

Building and Customization

Players will have the opportunity to engage in the construction and customization of these outposts, potentially influencing their functionality and defense against the dangers of Europa.

A Mysterious New Faction

The Descendants

The expansion introduces a new antagonistic force known as The Descendants. This faction is described as mysterious and is poised to significantly alter the dynamics and challenges faced by players navigating Europa's oceans.

What impact do The Descendants have on the world?

The presence of The Descendants is expected to shake up the established order, presenting new threats and potentially new narrative elements for players to uncover.

Integration with the Base Game

As an expansion, this content is designed to integrate seamlessly with the existing Barotrauma game. It does not function as a standalone title and requires ownership of the base Barotrauma game to access its new content and features.

Release Information

This expansion is scheduled for release on PC (Microsoft Windows) in late 2026. It is being developed by FakeFish and Undertow Games, with publishing by Daedalic Entertainment.
