    About

    Polar's Exploration Additions expands Minecraft exploration with new places to discover, challenges to face, and vanilla-plus building and loot options. Its biomes include scrubland, old growth savanna, volcanic mountains, amethyst caves, bioluminescent caves, crumbling caves, and crystalline caverns, alongside old growth forests with larger trees, mushrooms, bushes, and tall flowers. Explorers can find sites and features such as desert, badlands, and jungle obelisks, complex witch huts, underground ruins, a greenhouse, a skeletal outpost, and End ruins and mines. The mod adds creatures including fireflies, frostbitten, crystalline mimics, constructs, sculk squids, lava beetles, spirits, cursed eyes, Endermite Queens, and poltergeists, as well as a boss. It also revamps the End and adds distinctive weapons, potion variants, modified loot tables, and extra stone, wood, and other building materials for construction.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 1 area: World generationChanges 1 game code file in this area: terrain, biomes and structures made when new land is created..

    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. 3 files 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 · All 5 latest files checked, last on 22 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.
      5 latest files: the newest file for each Minecraft version and loader. All 5 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.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.

      code differs in 2 releases

    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 · All 5 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 all 5 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.
