Hello, Slugcats!
The modding community has given many players plenty of reasons to put countless additional hours into playing Rain World and it has honestly blown our minds to see the community’s ideas come to life in game. I’ve watched the progress of different mods being developed and have personally worked with different modding projects from the community. To put it in no uncertain terms, we at Akupara Games support the modding community of Rain World.
For this devlog, I’m excited to announce that Steam Workshop support will be coming to Rain World! Modders of Rain World will be able to upload their mods to Steam Workshop to enable more players easy access to their mods. Modders will have an easier time getting updates for their mods to the community.

On the player’s side, Rain World will be updated to include an in-game mod loader! You will not have to purchase Downpour to have access to the mod loader as this will be part of a free patch that will be added to the base game of Rain World! This will allow players to customize the mods they’ve subscribed to from the Steam Workshop in-game without having to manually move or manipulate files. Toggle what mods you want active, click the “Apply Mods” button, and it is as simple as that. You will also use this menu to toggle the More Slugcats Expansion and Jolly Co-Op coming in Rain World: Downpour, when the DLC is installed! If you have mods that might conflict with each other then the mod loader also allows you to adjust load order to configure which mods have priority over the others!
Those who have modded Rain World before, or who have made mods for it, will be familiar with ConfigMachine, a framework created by topicular that allows configuration menus to be made for mods. Rain World’s new in-game mod loader was a joint creation between topicular and Andrew, and all of the same capabilities of ConfigMachine will still be available and built into Rain World for mod creators to make configuration interfaces for their mods, and for players to tweak settings for their installed mods.
Some folks will be worried that this update will break the mods that are currently available, and unfortunately that is the case. However Andrew, the lead developer of Rain World: Downpour, will be working with modders to help them upgrade and transfer their mods to work with Steam Workshop. So once this goes live, many mods will already be ready to be uploaded to Steam Workshop and work with the mod loader. For now, modders can start reading this
technical reference to start to learn how to upgrade their mods, and about how the modding landscape will change in the new update.
In the meantime, if you would like to try out some of the mods that work with the current version of Rain World, then I would strongly recommend checking out
RainDB created by Andrew and
Custom Region Support created by Garrakx! Both of these are websites / databases made to host the different mods made by members of the Rain World community (And now the authors of these sites are working with Akupara to bring Downpour to players!). There are loads of mods available to play right now, including different slugcats, regions, modes, and more made by the community!
Well that is it for the devlogs for Jolly Week of July but tomorrow we will have a live stream! Join us tomorrow at 11 PDT on the
Akupara Twitch channel to get an early sneak peek at Co-Op Mode as we try to figure out how to traverse through the world with friends.
Thank you all for an amazing week! Let me know if you have any questions with the Steam Workshop and I’ll be happy to answer anything that I can!
