FakeFish and Undertow Games have announced a new expansion for multiplayer co-op submarine survival game Barotrauma. Titled Home & Harbor, the expansion will bring with it a host of new features, including the ability for players to take ownership of outposts, as well as the ability to build and manage these outposts.
Barotrauma: Home & Harbor was announced with a trailer during PC Gaming Show 2025. While we didn’t really get a look at the trailer, we did get a glimpse at the new faction that will also be coming to the game with the expansion – the Descendents.
The Descendants are a body-modified and technocratic faction that make use of alien technology. Thanks to the addition of the faction, players will also ultimately be able to get their hands on strange new tools and weapons to use.
Along with trying to build out an outpost, players will also need to manage NPC inhabitants and even establish industry to ensure the prosperity of the base. New technologies can also be researched through a dedicated technology tree.
Barotrauma: Home & Harbor will be coming to PC in 2026.
