Slime Rancher 2 Multiworld Setup Guide

Required Software

• Slime Rancher 2 (Steam)
• BepInEx-Unity.IL2CPP x64, bleeding-edge build v755: Windows and Linux, MacOS
• The .apworld file and the SlimeRancher2-AP mod, both from the SlimeRancher2-AP GitHub releases page

Installation

1. Install BepInEx

1. Download the BepInEx build for your OS from the links above.
2. Extract all of the BepInEx files into the game's root folder — the one containing the game's .exe. For Steam users, this is the folder that opens when you right-click Slime Rancher 2, select Manage, then Browse local files.
3. Linux players only: add WINEDLLOVERRIDES="winhttp=n,b" %command% to the game's Steam launch options. To do this, right-click Slime Rancher 2 in Steam, go to Properties, and enter it under Launch Options on the General tab. (Thanks to izzy for the troubleshooting on this!)
4. Launch the game once, then close it — this lets BepInEx generate its folder structure.

2. Install the SlimeRancher2-AP Mod

1. Download the mod archive from the SlimeRancher2-AP releases page.
2. Unzip the mod folder into BepInEx/Plugins inside your game folder.

Connecting to an Archipelago Server

1. Open Slime Rancher 2 and go to Settings. There should be an Archipelago menu option.
2. Enter your connection details (host, port, and slot name) and connect to the server. You must connect before starting a new game — connecting after the fact will not bind an existing save to your AP session.
3. Once connected, start a New Game in the slot of your choice and enjoy!

Configuring Your YAML

Download a template YAML from the Archipelago settings page and edit it to your liking. Key options:

Option	Description
goal	Win condition — labyrinth_open, newbucks, prismacore, or slimepedia
randomize_pods	Include Treasure Pods as location checks (default: on)
randomize_gordos	Include Gordo Slimes as location checks (default: on)
randomize_map_nodes	Include Map Data Nodes (default: on)
randomize_slimepedia	Include Slimepedia Slimes entries as location checks (default: off)
randomize_slimepedia_resources	Include Slimepedia Resources entries as location checks (default: off)
randomize_research_drones	Include Research Drones and their archive pages (default: off). Requires the Drone Archive Key item for archive checks.
randomize_ghostly_drones	Include Ghostly Drones (default: off)
region_access_mode	vanilla — gates work as normal (default); locations — gates are blocked until Region Access item received; bundled — same as locations, also grants zone teleporter blueprint on access
conversation_checks	Which rancher conversation gifts become location checks (none / conditional / all)
death_link	Dying sends a death to all DeathLink players (default: off)

Offline Play

The mod supports offline play. If you lose your connection mid-session:

• Location checks are saved locally and flushed to the server when you reconnect.
• Item notifications from scouted data are shown even while offline.
• Your save slot binding persists — just re-open the game and the mod will reconnect automatically on load.

Troubleshooting

The Archipelago tab is not showing in Options : Confirm BepInEx loaded the mod by checking BepInEx/LogOutput.log for a line like [Info : BepInEx] Loading SlimeRancher2-AP.

"Could not connect" error : Verify the host, port, and slot name are correct. Ensure the server room is open and the game name is Slime Rancher 2.

Items are not being received : Make sure you started a New Game after connecting — existing vanilla saves are not bound to an AP session.

BepInEx is not loading : You must use the IL2CPP x64 BepInEx build. The Mono (BepInEx 5) build is not compatible with Slime Rancher 2.
