    About

    Zombie Apocalypse Addon turns Minecraft into a configurable zombie-survival world, bringing ongoing danger to the daytime as well as the night for survival servers and apocalypse packs. It creates custom zombie waves around players, with adjustable spawn frequency, wave size, distance, nearby pressure, daylight rules, and protections that normally keep custom spawns out of torch-lit areas. Natural or manually triggered hordes and blood moons intensify attacks, while administrators can schedule hordes for dawn or dusk and tune event chances, size, duration, and pressure. Difficulty can grow with the in-game day through boosts to zombie health, damage, speed, armor, and equipment, either gradually or in steps; armor and weapon tiers increasingly favor stronger gear as the apocalypse progresses. The gear system can use items from other mods, and the addon also supports modded zombie entities, including through compatibility handling for mods such as Zombie Awareness, Zombies Reworked, The Hordes, and Improved Mobs. Optional siege mechanics let zombies break blocks, place limited blocks to cross gaps or climb, or form moving stacks to scale defenses, and these abilities can be reserved for hordes and blood moons. Another optional system lets zombies hunt animals and eat dropped meat, gaining lasting strength; well-fed zombies can persist, drop extra loot, and become door-breaking leaders that call reinforcements. Other features include biome-aware Husk and Drowned spawns, optional custom spawning in the Nether and End, zombie horses raised from killed horses, and kill tracking with advancements at 250, 1,000, and 3,000 kills. Presets offer casual, standard, and hardcore play, while server administrators can adjust settings live and tune behavior by zombie variant, attribute, biome, and dimension; destructive siege options and animal hunting are disabled by default.

    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.

    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 4 latest files checked, last on 24 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.
      4 latest files: the newest file for each Minecraft version and loader. The answer above is about the 3 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.
      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 · All 3 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 3 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 so far that AI was used to make it

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

    We have not read its code history 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.
