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

My guess is the option setup that should pop up on screen sometimes doesn't load for whatever reason. Try spamming F and see if it triggers the intro scene.
