- Anomalous Coffee Machine Not Safe edition is the adult-rated version of HoruBrain's word-input horror game.
- Separate product: it is not part of the free-to-cheap base game on Steam or the standard itch.io page.
- Age-gated access: purchasing requires an adult account on the storefront that hosts it.
- SFW wiki policy: this wiki covers mechanics only and does not describe adult content.
- Same core loop: word input, transformations, endings — the edition changes rating, not the core gameplay.
What the Not Safe Edition Is
The Anomalous Coffee Machine Not Safe edition is the mature-rated variant of HoruBrain Interactive's SCP-294-inspired horror visual novel. In the base game, you type any word into an anomalous vending machine, it dispenses a matching liquid, and the character drinking it reacts with color changes, transformations, and branching story outcomes. The developer reports 730+ discoverable words, 680+ transformations, and 200+ animated scenes across the project.
The Not Safe edition exists because of how the game was distributed. The base game launched on itch.io and later on Steam in March 2025, where it earned a Very Positive rating from over 1,600 reviews. Adult-oriented variants of the game are distributed separately on age-restricted storefront pages, and the sequel, Anomalous Coffee Machine 2 (released December 2025), similarly offers NSFW DLC as a separate, gated product.
This wiki is strictly SFW. We document the existence of the Not Safe edition, its availability, and its age requirements — but we do not describe, quote, or link to its adult content.
The table below summarizes how the editions relate to each other:
| Edition | Platform | Rating Tier | Core Gameplay |
|---|---|---|---|
| Base Game | Steam / itch.io | Standard | Word input, transformations, endings |
| Not Safe Edition | Age-gated storefront page | Adult (18+) | Same core loop with mature content |
| ACM2 + NSFW DLC | Steam (DLC sold separately) | DLC gated by age verification | Sequel content, new characters |
How the Editions Differ
For players deciding which version to buy, the differences come down to distribution, price structure, and content rating — not the underlying word-machine mechanic.
Steam Base Game
- Standard rating, safe for general audiences
- Achievements and cloud saves
- Very Positive reviews (1,600+)
- Regular patches and devlogs
itch.io Base Game
- Free-to-cheap entry point
- Developer devlogs posted here first
- Mod support (custom words/events)
- Latest public version: v0.9.4
Not Safe Edition
- Adult rating, 18+ verification required
- Sold on a separate gated page
- Not covered in detail on this wiki
- Same word-input core loop
A few structural facts are worth knowing before you buy:
| Aspect | Base Game | Not Safe Edition |
|---|---|---|
| Availability | Steam, itch.io | Age-gated store page |
| Age requirement | Standard | 18+ with verification |
| Word discovery system | 730+ words | Same discovery system |
| Endings and achievements | Full set | Parallel content set |
| Wiki coverage | Full guides | Edition facts only |
If you are here for the word-experimentation gameplay, transformations, and endings, the Steam base game delivers the complete core experience. The Not Safe edition only matters to adult players specifically seeking mature content.
How to Access the Right Version
Follow these steps to make sure you purchase the edition you actually want, on the correct storefront and with the right account settings.
Verify Your Storefront Account
Before anything else, confirm your account on Steam or itch.io is in good standing. Adult-gated pages on itch.io require an account with age verification enabled before the page even becomes visible.
Open the Official Store Page
Start from the official Steam page or the itch.io page. These are the only confirmed legitimate distribution points for the game and its variants.
Check the Developer's Links for Variants
HoruBrain lists its full catalog, including any adult-rated releases, through its official pages and the developer Discord. Do not trust third-party download mirrors claiming to offer "unlocked" editions.
Purchase and Install
Complete the purchase on the storefront hosting the edition you chose. Steam installs automatically; itch.io provides a downloadable build plus the optional itch.io app.
Join the Community for Updates
The developer posts new words, endings, and patch notes through Steam news, itch.io devlogs, and Discord. Follow at least one channel to track content updates.
Any site offering a "free Not Safe edition download" outside the official storefronts is almost certainly pirated or malicious. The base game is inexpensive and frequently updated — buying it directly is the safe route.
Core Gameplay Shared by All Editions
Regardless of edition, every version of Anomalous Coffee Machine runs on the same SCP-294-style system. Here is what the mechanics look like in practice, using well-known safe inputs as examples:
| Input Word | Output Liquid | Effect Type | Risk Level |
|---|---|---|---|
| coffee | Regular Coffee | Baseline / safe | ★☆☆☆☆ |
| milk | Milk | Color change, softening | ★☆☆☆☆ |
| water | Water | Neutral / state reset | ★☆☆☆☆ |
| rainbow | Rainbow Liquid | Cycling color palette | ★★☆☆☆ |
| gold | Liquid Gold | Rare visual transformation | ★★☆☆☆ |
| blood | Blood | Dark reaction, hidden events | ★★★★☆ |
Key mechanics that carry across editions:
- Effects stack: consecutive drinks interact, so input order matters for transformation outcomes.
- Dialogue is your feedback loop: the character's reactions after each drink hint at which ending route your session is building toward.
- Hidden triggers exist: repeated identical words, contradictory word pairs, and ending-gated inputs all unlock rare events.
- No fail state for experimenting: typing unusual words is the intended progression method.
Because the core loop is identical, every SFW guide on this wiki — word lists, tier rankings, endings walkthroughs — applies to the base game experience that all editions share.
Safe Exploration Checklist
Before diving into any edition of the game, run through this quick checklist:
Pre-Purchase and Setup Goals:
- Confirm which edition you want before purchasing
- Verify your storefront account and age settings
- Buy only from official Steam or itch.io pages
- Back up saves before experimenting with rare words
- Follow official devlogs for new word additions
Once purchased from an official channel, you are ready to experiment. Start with safe words like coffee and milk, then escalate toward hidden triggers as you learn the machine's behavior.
FAQ
Q: Is the Anomalous Coffee Machine Not Safe edition a separate game?
Yes. It is distributed as a distinct, age-gated release rather than an update to the base game. The Steam and standard itch.io versions of Anomalous Coffee Machine remain standard-rated experiences.
Q: Can I play the normal version and ignore the Not Safe edition entirely?
Absolutely. The base game on Steam and itch.io contains the complete word-input mechanic, 730+ discoverable words, transformations, and endings. Nothing in the base experience requires the adult edition.
Q: Is the Not Safe edition free?
No reliable source indicates it is free. Adult-rated variants are sold through age-verified storefront pages, while the base game itself has a low price point on Steam with a free tier history on itch.io. Avoid any site claiming otherwise.
Q: Does this wiki cover the Anomalous Coffee Machine Not Safe edition content?
No. This wiki is strictly SFW by policy. We document the edition's existence, access requirements, and how it relates to the base game, but all guides — words, transformations, endings, and achievements — focus on the standard release.
