Before You Begin
Requirements & Preflight
What you need, why the 64-bit Mono build is the only correct choice, and how to find your game folder.
This whole guide takes about ten minutes. Before you touch a single file, line up the six things below and confirm you understand the one decision that matters: BepInEx 5, 64-bit, Mono. Get that right and the rest is copy-and-paste.
What You Need
A copy of Devilated
The PC build that launches through Devilated.exe. This guide was written against retail v1.0.2. Any close version works the same way.
BepInEx 5 — 64-bit
Specifically BepInEx_win_x64_5.4.23.5.zip (the win_x64 build). Devilated is a 64-bit Unity game, so the x86 pack will silently do nothing.
The Mono runtime — not IL2CPP
Devilated ships a MonoBleedingEdge folder, which means it is a Mono game. Use BepInEx 5. Do not use a BepInEx 6 IL2CPP pack — the plugin will not load.
The GoreAtmosFX package
The StixsworldHD_Devilated_GoreAtmosFX_v1_1_0.zip download from this site (or your own copy of the RAR). It contains the plugin DLL and this README.
An archive extractor
7-Zip, WinRAR or Windows’ built-in ZIP support — anything that can unpack a .zip and a .rar.
A plain-text editor
Notepad is fine; Notepad++ or VS Code make the heavily-commented config file far easier to read and edit.
Mono, Not IL2CPP
BepInEx ships in two families. BepInEx 5 targets Unity games built on the Mono scripting backend. BepInEx 6 exists mainly to support games compiled with IL2CPP, a completely different runtime.
Devilated is a Mono game. The dead giveaway is right there
in the install folder: a MonoBleedingEdge directory sits next to
Devilated.exe. That folder is the Mono runtime. So the
GoreAtmosFX plugin is built as a BepInEx 5 Mono plugin, and only a BepInEx 5
build will load it.
Find the Game Folder
Every file in this guide lands in one place: the folder that contains
Devilated.exe. In Steam, right-click
Devilated → Manage → Browse local files and Explorer opens
there directly.
On the machine these screenshots come from, that path is:
…\SteamLibrary\steamapps\common\Devilated\
Full sizePreflight Checklist
- I have Devilated installed and can find
Devilated.exe. - I downloaded BepInEx 5, the win_x64 build — not x86, not version 6.
- I have the GoreAtmosFX package (
StixsworldHD_Devilated_GoreAtmosFX_v1_1_0.zipor my own RAR). - I have an archive extractor and a plain-text editor ready.
