    About

    Alpha Below adds a quiet, buried Alpha-style dimension beneath the Overworld, built for atmospheric exploration rather than combat-focused play. Its old terrain includes wormlike caves, configurable Far Lands, and three biomes: Alpha Forest, Alpha Desert, and Alpha Snowy. Exploration reveals brick pyramids, obsidian walls and monoliths, campsites, abandoned developer houses, rare player remains, and floating chopped trees that suggest earlier visitors. The dimension changes the look and sound of play with classic block and item textures, harsher old-school lighting, heavy fog, and C418-era music. With Immersive Portals installed, the dimensions can be vertically stacked so players can break through and descend into the world below without a conventional portal transition. The dimension also adds ruby ore and recipes for Alpha-exclusive ruby tools and armor, with JEI support for viewing crafting and smelting recipes. Optional, disabled-by-default eerie systems include the Lost Voyager, whose shrines can accept offerings and later leave messages or loot, and 2Char, a distant anomaly that can leave environmental traces. Settings let players adjust features such as landmark generation, Far Lands distance, the bedrock ceiling, and whether the dimension has a day-night cycle.

    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 · Both latest files checked, last on 16 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. Both are for recent versions. 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.

      Nothing declared about your system outside the game.
    • 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 · Both files 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 both files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and sounds and found none.

    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.
