Turn a stock museum into an
ungodly one — step by step.
A complete, no-guesswork walkthrough for installing a BepInEx 6 (IL2CPP) loader that's been pre-configured specifically for Two Point Museum — then dropping in the Ungodly AI, Staff, Crime & Economy Overhaul plugin. No BepInEx setup to do yourself; two clean phases, every file accounted for, with the real install screenshots as your map.
Two artifacts, one museum
What goes into the game
The mod can't run on its own — it's a guest that needs a host. You install the host first (the loader), then the guest (the plugin). Here's what each one is.
1 · BepInEx 6 — the loader
BepInEx is a mod framework for Unity games, and this copy has been configured specifically for Two Point Museum — it's the IL2CPP branch (bleeding-edge build be.784) to match this game's native-compiled build, with its Doorstop loader pre-set and its Unity support libraries pinned to the game's exact engine (6000.0.63). You don't configure anything; you just drop it in.
It hooks in through a winhttp.dll proxy + Unity Doorstop 4.5.0,
loads a bundled .NET 6 runtime, and on first launch generates the
interop assemblies that let managed plugins talk to the native game.
2 · Ungodly AI — the plugin
A single BepInEx plugin, StixsworldHD.UngodlyAI.TPM.dll, that rebuilds how a museum
runs: guest needs & behaviour, knowledge/buzz/prestige, research, staff wages &
coverage, item upkeep, and a full economy — plus four real-time "director" systems.
Every value is exposed in a documented config file and a built-in in-game window (F6). 67 settings across 13 sections, each with a plain-English explanation and a safe range. One switch flips the whole thing back to vanilla — no restart.
The exhibit, in brief
Six pillars & four live directors
You don't need to know any of this to install it — but here's what you're switching on. Every lever drives a real game system verified in the shipping build; there are no placeholders.
Guests
Per-need build-up speed (food, drink, toilet, energy, entertainment, litter, environment), warning/urgent thresholds, importance and capacity.
Knowledge & prestige
Exhibit knowledge-level scaling, knowledge-rating and theme-knowledge gains, and museum prestige gains.
Research
How quickly your experts push research and analysis forward at the study desks.
Staff
Global wage multiplier, desired-salary scaling, optional movement speed — plus live coverage & auto-raise systems.
Items & upkeep
How fast exhibits and equipment wear down and need maintenance.
Economy
Income multiplier, sell-value, a fixed ticket-price override, a one-time grant and a recurring monthly stipend.
The four "Ungodly" directors
Difficulty Director
Closed-loop rubber-banding that holds your museum at a target happiness.
Coverage Helper
Speeds staff up automatically when the museum gets busy or under-served.
Crime & Security
Reveals (and optionally evicts) disguised thieves through the game's own crime systems.
Auto Pay-Raise
Tops underpaid staff toward what they want so they stay happy.
Before you start
What you need
- Two Point Museum on PC (Steam), 64-bit — base game and all DLC are supported.
- A file archiver that opens .rar (WinRAR or 7-Zip).
- Write access to the game's install folder (where
TPM.exelives). - Both downloads from the manifest below (or your own copies).
- ~50 MB of free disk space for the loader and its runtime.
Common mistakes
It won't load if…
- You use BepInEx 5 (the Mono line). This plugin targets the IL2CPP Il2CppInterop runtime — only BepInEx 6 IL2CPP works.
- You skip the first launch after installing BepInEx, so the
interopassemblies never get generated. - You extract into a subfolder instead of the game root, so
winhttp.dlldoesn't sit next toTPM.exe. - You drop the plugin into
coreorpatchersinstead ofplugins.
Acquisition manifest
The files, bundled
Everything referenced in this guide ships inside it, so you never have to hunt for or set up a loader. The BepInEx archive below is already configured for Two Point Museum — grab both archives and you'll extract the first in Phase 1 and the second in Phase 2.

🛟Save-safe, always reversible
The mod never writes anything into your save — it only changes live, in-memory values. Uninstalling is deleting the DLL. Nothing here can corrupt a museum. Ready? Head to Phase 1 →
