This Minecraft map recreates the game Subnautica in Minecraft.


is an underwater adventure/survival game set on an alien ocean planet, developed and published by Unknown Worlds Entertainment. Read more. I strongly recommend checking out Subnautica if you haven't heard of it yet.

This Project is a terrain based on 4546B - the ocean planet, where Subnautica takes place. It is also survival compatible.
Please note all the names (e.g. plants, animals, places, objects) belong to Unknown Worlds Entertainment. Subnautica.

The download comes with a default resource pack. You can get a higher quality pack if you can handle it (up to 4x the resolution) here.

Also, keep in mind that this is Early Access. There are likely many bugs that need to be found and fixed. If you come across something that doesn't seem right, write about it in the comments.

If you experience very low FPS during gameplay, you might want to allocate more memory to Minecraft.
To fix server-side lag, such as mobs freezing, laggy animations, etc. give the server more memory. In Project Files, create a text file with 'javaw -Xmx2048M -Xms2048M -jar spigot-1.12.2.jar' inside. Save it as .cmd and run it to run the server with 2G of memory.

This is a video installation guide. The installation is complicated, but everything is shown clearly. It shouldn't take longer than a few minutes. There's also a written guide in the All Files.zip file you get from the download.

Please be careful at the plugin downloading step. Check if you have 15 plugins downloaded before closing the browser. If not, click on all the tabs to refresh them. Also, in the video, it looks as if Minecraft launches itself, but actually, it's just a cut in the video to make it shorter. You have to launch Minecraft normally by hand like you always do.

Below you can find a tutorial for Multiplayer Support. It uses Hamachi, free software that allows your friends to join your private Minecraft server. Click to download Hamachi. Keep in mind you need to follow the normal installation guide before proceeding to Multiplayer.

Of course, you can host the server in a different way. Using Hamachi is just a suggestion for playing with friends. Please don't open public servers using this setup.

This Project uses Spigot as its engine, and some Spigot plugins: CrackShot, FastAsyncWorldEdit, GroupManager, Holograms, LibsDisguises, message-blocker, MythicMobs, ProtocolLib, SharpSK, Skellet, SkQuery, SkRayFall, Skript, skript-mirror, skUtilities.

All of these are downloaded from the official websites, to honor their authors.
The recommended shader for this project is CPHSBC Shader by Crushed Pixel

This looks so cool, but I cannot get one of the final steps to work. When I try to run the server by double clicking "spigot-1.12.2.jar", nothing happens. No extra files are generated and I'm pretty sure the server isn't started cause it says "cant connect" in Minecraft. I am running it with Java(TM) Platform SE Binary as well, not WinRar. Any help possible?

Please help! Whenever I join the server, the game immediately crashes. And now the the server won't even connect anymore.

This is really cool, too bad it's before Minecraft had swimming mechanics though.

True. I thought about a modern remake... but now can't say for sure if that will happen

That would be a lot of work just to add 1.13 swimming mechanics. Could anything just directly work? Or would every file have to be dug through and remade?

It would require some digging because of the command syntax change in 1.13, and some plugins might work differently as well. I think if I were to remake it, I would code it on pure Java from scratch. Much more efficient, less problematic, stable, and long-lasting. I would leave the map, most sounds, and textures as they are. So primarily focus on code.
