What Is Anomalous Coffee Machine on itch.io?
Anomalous Coffee Machine is an indie horror visual novel by developer HoruBrain, inspired by the classic SCP-294 vending machine. You type any word into a keypad, and the machine dispenses a liquid matching that word. The character sitting with you drinks it — and transforms. The itch.io page at horubrain.itch.io/anomalous-coffee-machine serves as the game's original home, where it was playable for free before the March 28, 2025 Steam release.
The itch.io version remains the go-to place for players who want the base experience at no cost, plus early access to devlogs and community mods. The official trailer from HoruBrain Interactive gives a quick look at the machine in action.
Video Highlights:
- See the word-input mechanic and keypad in action
- Preview transformation effects on the main character
- Get a feel for the game's late-night horror atmosphere
Head to the official page at horubrain.itch.io/anomalous-coffee-machine and download the latest public build. The developer's Discord (discord.gg/horubrain) is linked from the store page for updates and mod discussion.

How to Download and Set Up on itch.io
Getting started takes only a few minutes. Follow these steps to install the itch.io build and run your first experiment session.
Visit the Official Page
Go to horubrain.itch.io/anomalous-coffee-machine. Verify the developer name is HoruBrain to avoid unofficial mirrors.
Download the Latest Build
Grab the current public version (v0.9.4). The game is built on the Godot engine, so Windows, macOS, and Linux builds may be offered depending on your platform.
Extract and Launch
Unzip the download to a folder of your choice and run the executable. No installer is required — the game runs standalone.
Run Your First Session
Start with safe words like coffee or milk to learn the input flow, then escalate to bolder vocabulary as the character reacts.
Check Devlogs for Updates
Revisit the page's devlog tab regularly — new words, endings, and reaction dialogue are added in ongoing patches.
The game stores saves under Godot's user data directory (app_userdata). Back this folder up before experimenting with mods or major updates so you never lose your discovered-word progress.
Core Mechanics and What to Type First
Every session revolves around the machine's word-dispensing system. Effects stack over a session, and the character's dialogue after each drink is your main feedback loop for hidden events and ending routes.
Here are the best starter words, ranked by community feedback:
| Input Word | Output Liquid | Effect Type | Tier |
|---|---|---|---|
| rainbow | Rainbow Liquid | Cycling color transformation | S |
| gold | Liquid Gold | Rare visual transformation | S |
| blood | Blood | Dark transformation route | A |
| coffee | Regular Coffee | Baseline / safe test | A |
| milk | Milk | Light color softening | B |
| water | Water | Neutral / state reset | B |
Feeding the machine the same word three times in a row triggers a glitch anomaly — the machine comments on your persistence and serves a stabilized result instead of a third transformation.
First Session Goals:
- Serve the baseline coffee word
- Trigger one color-change transformation
- Trigger one body transformation
- Unlock a hidden event with a rare word
- Reach your first ending
Mods, Community, and the Series Roadmap
The itch.io version is the most mod-friendly build of the game. Players can create custom words and custom events, which is a major reason the community stays active on the platform even after the Steam launch.

|---|---|---|
| itch.io devlog | Patch notes, new words | horubrain.itch.io/anomalous-coffee-machine/devlog |
| Discord | Official community and mods | discord.gg/horubrain |
| Steam discussions | Endings and word findings | steamcommunity.com/app/3173560 |
| General horror discussion | r/indiehorror, r/SCP |
The franchise is expanding: Anomalous Coffee Machine 2 launched on Steam in December 2025 (AppID 3797340), and ACM3 has an official trailer as of 2026. The itch.io original remains free and actively patched.
