    • Better Mineshafts

    About

    YUNG's Better Mineshafts overhauls vanilla abandoned mineshafts, replacing straight corridors with varied, interconnected tunnel networks across 13 biome variants, including a rare mushroom mineshaft. Exploration can uncover loot at abandoned workstations, less common workstation cellars, and chests on minecarts, as well as abandoned miners' outposts and rare openings to the surface. Some tunnels end at ore deposits containing coal, iron, redstone, gold, lapis, emerald, or, very rarely, diamond. Mineshaft generation is customizable through the mod's configuration folder, and the mod is intended to work alongside world-generation mods including YUNG's Better Strongholds, Better Dungeons, YUNG's Extras, and YUNG's Bridges.

    Written from CurseForge . How we write it

    In-game changes

    Changes the game's code in 3 areas: World generationChanges 1 game code file in this area: terrain, biomes and structures made when new land is created., Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses. and Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules..

    Adds:

    • 13 structuresMineshaft Acacia, Mineshaft Desert, Mineshaft Dripstone, Mineshaft Ice, Mineshaft Jungle, Mineshaft Lush, Mineshaft Mesa, Mineshaft Mushroom and 5 more.

    Counted from the files of the mod. Content made only in its code is not counted.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · The latest file checked, last on 15 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      2 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Its one file read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of its one file, for recent Minecraft versions. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files, images, code history and pull requests and found none.

    We have not read its changelogs yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
