Deep Blue: Ocean Survival
by FunkyToc
Deep Blue: Ocean Survival turns the world into a submerged, ocean-only setting where players start on floating wood under water and work toward land.
What it does
The world is covered by water, with shallows about 20 meters deep and abysses past 300 meters. Rare emerged islands break the surface. Player buoyancy changes with the depth of the current, and the default oxygen supply lasts about 30 seconds before air runs low. Recipes are included to help with the first steps of the journey, and advancements follow a guide-style progression.
The mod is a data pack and is required on the server, so the server must run it. Clients may join without installing anything, though a client can add it. Deep Blue is published for Fabric, Forge, NeoForge and Quilt across the 26.1 – 26.2 range, with files for 26.1, 26.1.1, 26.1.2 and 26.2. It is licensed under Creative Commons Attribution No Derivatives 4.0 and is not open source.
Key features
Submerged ocean world
Terrain generation covers the world with water, with shallows and deep ocean replacing the usual land.
Depth-based buoyancy
Player buoyancy changes with the depth of the current, so movement feels different from the surface to the abyss.
Guided progression
Achievements and advancements follow the guide, so each stage of survival comes in order.
Few structures
Only a small number of structures generate, including floating wood platforms that form the spawn point.
