Regions Unexplored is a biome mod for Minecraft Java Edition that overhauls Overworld and Nether generation with 64 new biomes, plus new blocks and items. Fabric and NeoForge builds run through 26.1.2. Current versions need Lithostitched, and on Fabric also Fabric API. The mod must be installed on both the client and the server.
Biomes and what the mod adds
The 64 biomes are spread across the Overworld and the Nether. The mod has no wiki and no full up-to-date biome list, so the count is the reliable number. The developer answers questions and posts updates on the project's Discord. The newest 0.7.0 builds for 26.1 are labelled beta, so expect rough edges on the latest versions.

Questions about Regions Unexplored.
5 questions
How do I install Regions Unexplored?
Pick the build that matches your loader and Minecraft version, then add its dependencies. Current builds need Lithostitched, plus Fabric API on Fabric. Put every .jar in the mods folder and launch the loader's profile. It is a Java Edition mod, so Bedrock Edition cannot load it.
Which Minecraft version does Regions Unexplored support?
Fabric builds cover 1.19.2 to 26.1.2 and NeoForge builds cover 1.21 to 26.1.2. The newest 0.7.0 builds are betas for 26.1, and 26.1.2 is the highest version either loader lists.
Does Regions Unexplored work on Forge or Quilt?
Only in older versions. Forge builds stopped at Minecraft 1.21.1 in March 2025, and Quilt builds stopped at 1.20.4 in March 2024. Both need TerraBlender. For anything newer than those versions, use the Fabric or NeoForge build.
Does Regions Unexplored work on multiplayer servers?
Yes, but it must be installed on the server as well as on every client, along with its dependencies. The mod is required on both sides, so a server without it will not work with clients that have it.
How many biomes does Regions Unexplored add?
It adds 64 new biomes across the Overworld and the Nether, along with new blocks and items. There is no wiki and no full up-to-date biome list, so the developer points players to the project's Discord with questions.
