ChunkBound is a survival progression modpack where your entire journey begins inside a single chunk. Everything outside is locked behind an invisible border – and the only way to expand your world is to earn new chunks one by one.

The modpack focuses on smart progression, limited space creativity, and gradually unlocking tech and automation. Each new chunk feels meaningful, and every decision matters when your space is this small.

As you grow, you’ll unlock:

  • better storage and logistics
  • ore processing and alloy forging
  • farming, automation, utilities
  • new mechanics introduced through quests

ChunkBound is simple at the start, but evolves into a surprisingly deep survival experience. If you enjoy slow but satisfying progression, compact bases and creative problem-solving, this pack is made for you.

PL

ChunkBound to paczka survivalowa, w której cała rozgrywka zaczyna się w jednym jedynym chunku. Reszta świata jest zablokowana za niewidzialną barierą – a Ty musisz odblokowywać kolejne chunki własną pracą.

Paczka skupia się na mądrym progresie, kreatywności w ograniczonej przestrzeni oraz stopniowym odkrywaniu technologii i automatyzacji. Każdy nowy chunk naprawdę coś znaczy, a każda decyzja ma wagę, gdy miejsca jest tak mało.

W trakcie gry odblokujesz:

  • lepsze magazyny i logistykę
  • przetwarzanie ród i tworzenie stopów
  • rolnictwo, automatyzację i przydatne narzędzia
  • nowe mechaniki prowadzone questami

ChunkBound zaczyna się prosto, ale przeradza się w zaskakująco głębokie survivalowe wyzwanie. Jeśli lubisz wyraźny progres, kompaktowe bazy i kreatywne podejście do ograniczeń, ta paczka jest właśnie dla Ciebie.

How to install ChunkBound

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the modpack for Minecraft 1.21.1 on Fabric automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Download the modpack archive

    In the version list above, pick the file ChunkBound 0.8.mrpack (354 MB).

  2. Import it into a launcher

    A launcher that supports modpacks (Millida Launcher, Prism) takes the archive via “Add modpack”, then “From file”. No need to unpack it yourself.

  3. Allocate memory

    Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.

On a server

  1. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.

  2. Invite friends: they install the same modpack

    To join the server, every player needs the same modpack version.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
