Dimension's Expanded
by MikuTheDev
Dimension's Expanded, a NeoForge adventure mod by MikuTheDev, adds three new dimensions to the game: a Mining Dimension, a Sea Dimension and a Fallen World Dimension.
What it does
Vanilla Minecraft has three dimensions: the Overworld, the Nether and the End. This mod adds three more, each with its own terrain and monsters. The Mining Dimension was made for players who want to gather resources without constantly searching for new caves, and the author describes it as a response to broken mining dimension mods. The Sea Dimension is a world of water, and the Fallen World Dimension is filled with monsters.
Dimension's Expanded is built for NeoForge 1.21.1 only and is published as a single file, version 0.1, released on 2026-01-10. The server and every player need the mod installed. The mod has no dependencies beyond NeoForge itself, and the code is covered by All rights reserved, so it is not open source. Interface text is available in English, Finnish and Russian.
Key features
Mining Dimension
A dimension built for mining, so resources can be gathered without travelling to new caves in the Overworld.
Sea Dimension
A dimension whose terrain is dominated by water, adding a new environment for exploration.
Fallen World Dimension
A dimension filled with monsters, intended for players looking for a harder place to explore.
Two default biomes
The mod adds two biomes to the default game, so the new dimensions have additional terrain variety.
