How to install Invincible Protocol

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 Forge or NeoForge 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 InvincibleProtocol-[1.0.5].zip (5.2 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.
