FusionCore
by Freki
FusionCore is a Forge mod for 1.20.1 that adds fusion reactors, a custom energy crystal and a storage system, with a dimension to explore.
What it does
The mod leans technical: two types of fusion reactor feed a storage system, and a custom energy crystal and a carpet-made crystal serve as components in the build chain. An Astral Window lets players look into a separate map of the new dimension, which holds a large amount of lore to explore.
Mysterious mobs roam the dimension, and a set of cosmetic additions sits alongside the technical content. Only the client needs the mod, so a server can run without it and players join without installing anything. The code is under the MIT License and is open source, with its source and issue tracker public. Files are published for 1.20.1 only, with the latest Forge file dated 2024-04-14.
Key features
Two fusion reactor types
Two kinds of fusion reactor are available, each producing energy used by the storage system and the crystal recipes.
Custom energy crystal
A crystal made for this mod serves as an energy component, and a carpet-based variant is crafted from the same line.
Storage system
A storage network built around the reactors keeps items organized, with the fusion equipment as its core.
Astral Window
The Astral Window opens a view into the dimension's maps, so players can study the terrain before traveling there.
Dimension with lore
A separate dimension carries a lot of lore, and its mysterious mobs give players reasons to explore it.
