How to install HReactor

  1. This modpack runs on Fabric and Forge for Minecraft 1.20 – 26.x. The launcher you install it with sets that up for you.

  2. Download the .mrpack file from Modrinth.

  3. Open it with a launcher that reads .mrpack files, such as the Modrinth App or Prism Launcher: it makes a new instance with every mod and setting of the pack.

  4. Give the instance enough memory: most modpacks want 4 to 8 GB.

  5. To play it with friends on a server, use the server files of the modpack if its page offers them; otherwise install the same mods on the server.
