Humanity has always dreamed of traversing the universe in search of unknown planets and moons. And now, this is to some extent possible in vanilla Minecraft!
The Expansion adds 7 space-related dimensions, more than 10 structures to find there, 3 vehicles, a lot of custom items, tools, weapons, machines...
... and a whole load of other features!
Getting started
- Look at The Moon at night with a spyglass while holding a book and quill in your offhand.
Other Information
- The datapack is multiplayer compatible.
- The datapack doesn't work on Minecraft Realms because it utilizes the 'experimental' custom dimension features.
- Do not remove The Expansion from your server once installed. Removing it will break your server.
- Please report any bugs you may find to my discord server.
