- Anomalous Coffee Machine mods let players add custom words and custom events to the machine.
- The base game ships with official mod support — 730+ words and 680+ transformations by default.
- Modding works best on the itch.io version; Steam support may vary by update.
- Always back up your save file before installing any custom word packs.
- Custom events use the same word-input mechanic, so no coding is required for basic packs.
What Are Anomalous Coffee Machine Mods?
Anomalous Coffee Machine is a word-experimentation horror game by HoruBrain, built on the SCP-294 concept: you type any word into a mysterious vending machine, it dispenses a matching liquid, and the character sitting with you transforms. Mods extend this core loop by letting players add custom input words and custom events beyond the official list.
According to the official itch.io page, the game supports modding for custom words and events on top of its already massive base content — 730+ discoverable words, 680+ transformations, and 200+ animated scenes. That means the modding scene exists to fill very specific niches: joke words, crossover references, and personalized transformation outcomes.
Because the entire game runs on typed vocabulary, a modded word list effectively expands the game infinitely. Even adding ten custom words can create reaction chains the base game never produces.
Base Game vs Modded Content
| Aspect | Base Game | With Mods |
|---|---|---|
| Input words | 730+ official words | Unlimited, community-defined |
| Transformations | 680+ variants | Custom variants per mod pack |
| Events | 200+ animated scenes | Custom event scripts |
| Dialogue | 100k+ official lines | Fan-written reaction lines |
| Cups & art | 150+ cup illustrations | Optional custom art packs |
| Platform | Steam & itch.io | Primarily itch.io build |
Types of Mods: Custom Words, Events, and Packs
Mod content in the Anomalous Coffee Machine community generally falls into four categories. Each modifies a different layer of the game's word-to-effect pipeline.
Custom Word Mods
- Adds new input words to the keypad
- Each word maps to a liquid and effect
- Easiest entry point for creators
- Great for joke and meme vocabulary
Custom Event Mods
- Scripts new scenes and reactions
- Can trigger on word sequences
- Enables branching mini-stories
- Requires more setup than word packs
Transformation Packs
- Adds new transformation forms
- May include custom art variants
- Often themed (color, size, style)
- Pairs with matching word lists
Quality-of-Life Mods
- Word discovery trackers and logs
- Faster menu navigation
- Save management helpers
- Popular with 100% completion hunters
This wiki covers mods in a strictly SFW scope. Some third-party adult content exists in the wider community for this game and its sequel — those are out of scope here. Stick to word packs and event mods from reputable, clearly-labeled sources.
Step-by-Step: Installing Mods Safely
Follow this process to install custom word or event mods without breaking your save data. The game stores saves under the Godot user data directory, so backups are cheap insurance.
Back Up Your Save Data
Locate the save folder under the Godot user data directory (app_userdata/AnomalousCoffeeMachine). Copy the entire folder elsewhere before touching any mod files. A malformed mod can corrupt session state.
Get the Base Game on itch.io
Download or update Anomalous Coffee Machine from the official itch.io page (https://horubrain.itch.io/anomalous-coffee-machine). The itch.io build receives devlog updates that document mod-related changes most frequently.
Download a Verified Mod Pack
Only grab packs shared through the developer's official Discord (https://discord.gg/horubrain) or linked in itch.io devlogs. Avoid re-uploaded packs from unverified mirrors — they may contain broken word definitions.
Install Into the Game Folder
Place the mod files in the game's mod or data folder as instructed by the pack. Most word packs are drop-in text definitions; event mods may add script files. Do not overwrite core game files.
Test Words in a Fresh Session
Start a new session and type one of the pack's custom words. Confirm the machine recognizes the input and produces the intended liquid and effect. If the UI glitches, remove the pack and restore your save backup.
Never install multiple event mods that define the same trigger word. Conflicting definitions can produce unstable results or crash the session. Test packs one at a time.
Creating Your Own Custom Words
Basic word mods are one of the friendliest entry points into game modding because the input system is text-driven. Here is the typical authoring workflow.
Mod Creation Workflow
| Stage | Task | Difficulty |
|---|---|---|
| 1 | Pick a word not in the official 730+ list | ★☆☆☆☆ |
| 2 | Define the output liquid and effect type | ★★☆☆☆ |
| 3 | Write character reaction dialogue | ★★☆☆☆ |
| 4 | Link an event or animation trigger | ★★★☆☆ |
| 5 | Package and test in a clean save | ★★★☆☆ |
| 6 | Share via Discord or devlog feedback | ★☆☆☆☆ |
Several official word additions came directly from community suggestions in post-launch devlogs. If your custom word is popular enough, it may be adopted into the base game in a future update.
Before Publishing Your Word Mod:
- Verify the word is not already in the official 730+ list
- Test the effect in a fresh session with a clean save
- Confirm no conflicts with other installed packs
- Keep content strictly SFW per community rules
- Include a short readme describing the effect
Platform Comparison and Compatibility
Not every platform handles mods identically. Here is how the main options compare for modding as of 2026.
| Platform | Mod Support | Notes |
|---|---|---|
| itch.io (PC) | Best | Official devlogs document mod features; most flexible |
| Steam (PC) | Partial | Works, but updates may overwrite mod folders |
| Sequel (ACM2) | Different ecosystem | Has its own DLC structure; separate mod scene |
| Steam Deck | Experimental | Linux file access possible but unsupported |
Steam patches can reset game folders and silently remove installed mods. Re-verify your mod folder after every update, and keep the original pack downloads archived.
