Nuclear Throne Randomizer Setup Guide

Required Software

Mod Installation

  1. Download the archipelago.mod zip folder from either itch.io or the Nuclear Throne Archipelago GitHub release page.
  2. Locate Nuclear Throne from within your Steam library
  3. Right-click on the game and select Properties
  4. Navigate to Game Versions & Betas and select ntt_development
  5. After the version is installed, right-click on Nuclear Throne in your steam library and navigate to Manage > Browse local files.
  6. From the window that pops up, find the mods folder or create one if it does not exist and extract the archipelago.mod zip folder into that folder.

Do I need to have every character already unlocked before I try this mod?

Yes, you will at the bare minimum need a NuclearThroneTogether.sav file with every playable character unlocked to play this archipelago. That's why .sav files are provided within the archipelago.mod zip folder with each character unlocked. Some files provided also have additional content unlocked including Skins and Crowns. To utilize the save file complete the following:

  1. With Nuclear Throne Together installed, navigate to your NuclearThroneTogether.sav file (%LOCALAPPDATA%/nuclearthrone on Windows)
  2. Replace your .sav file with one of the provided NuclearThroneTogether.sav files

Text Client Installation

  1. Download and install Archipelago (if you haven't done so already).
  2. Head on over to the Nuclear Throne Archipelago GitHub release page and download nuclear_throne.apworld.
  3. Open Archipelago and navigate to Install APWorld. Clicking Open will give you a file prompt where you will select the .apworld file you download earlier.
  4. Restart Archipelago and navigate to Nuclear Throne Client. Clicking Open will open the integration's text client, which you will use next to join a Multiworld.

Joining a MultiWorld

  1. In the text client, in the Server text field, input the Multiworld's server IP address and port (for example, archipelago.gg:8080) and click Connect.
  2. Enter the slot name chosen in your YAML file into the bottom text field and press Enter on your keyboard (if prompted, do the same thing with the server password).
  3. Open the game and select PLAY (the character you selected in your YAML will automatically be loaded).
