From Brotato Wiki
How do I download mods?
Click on a mod's name to view its page. Downloads are always in the "Downloads" section of each mod page.
Where is the Rainbow Chest / Crate mod / SIFD's Mod?
It's here: SIFD's Mod - Rainbow Chest
How do I install mods?
See Mod Installation on the main Modding page.
Can I use multiple mods at once?
No, nearly every mod is standalone and can't be used together with other mods.
There are two exceptions: Invasion and dami's Arsenal. These both use dami's multi mod script, which lets a mod load a ZIP of specially-prepared add-on files.
The multi-mod script can be added to existing mods if the mod creator wants to; however, nearly every mod can't be made into multi-mod compatible add-ons, because they modify vanilla code, and multi mod add-ons can't affect vanilla code.
Will there be Steam Workshop support?
The developer plans to add modding support, so eventually you might be able to.
Will mods ever be on Nexus or Thunderstore?
No. They will stay on the wiki until Steam Workshop support is added.
What are the best mods?
Every mod has something unique to offer, going as far back as the demo.
If you want to cheat, a lot of people like Rainbow Chest.
There are also loads of mods that add new content, and often add special custom effects. See Content Mods above on the main Modding page for the full list.
You can click the "Last Update" column to sort the table and see what's new (click it twice to show most recent). You can also sort by the "Game Version" to see which mods use the current vanilla patch.
Can I use outdated mods?
Yes, but they are locked to the patch version they were released on.
This is because mods are downloaded as PCK files, which replace Brotato.pck. These PCK files contain all the game's code and assets. The EXE is just the game engine that runs the code in the PCK.
This means that when you replace the PCK, you're replacing everything.
Is downloading mods safe?
The wiki's mod page downloads are relatively safe, because they can only be edited by modders and wiki admins, which means that random people can't just upload a virus.
The mods on the wiki are also usually made by long-standing members of the community.
However, as with downloading any software from the internet, you should still be careful.
How do I mod the game?
You'll need to know/learn Godot. You can start with Jonus' video here.
For something less technical, there's also a mod on the wiki called HerbLoader, which lets you create custom characters with JSON and PNG files.
