Oxide Room 104 is a first-person survival horror game that drops you into a rotting motel room with a locked door, a body horror nightmare on the other side, and a scientist who clearly has plans for you. We downloaded v1.0.5 through the direct GOG installer, ran it on a Windows 64-bit machine, and played through enough of the loop to tell you exactly what you are getting into. If you have been hunting for a puzzle-driven horror title that respects your time and your nerves, this one earns a close look.
This updated build (v1.0.5) keeps the same core experience that made the original release memorable, and the install package sits at a manageable 2.80 GB. Below you will find the download button, the real technical specs, our hands-on impressions, and the honest downsides we ran into.

What Oxide Room 104 Actually Is
Strip away the marketing and Oxide Room 104 is a tightly wound escape room wrapped in a horror shell. You wake up in room 104 of a decaying motel, kidnapped, with a grotesque creature roaming the halls and a cold-blooded scientist pulling strings somewhere out of sight. The premise borrows from body horror in a way that feels intentional rather than gratuitous, and it gives every puzzle a sense of dread that a plain escape room game could never pull off.
Your job is to search the room for clues and tools, combine what you find, and inch your way toward a way out. The gameplay loop is built on observation and experimentation. You will pick up items, inspect them, and figure out how they interact with the environment. Nothing is handed to you, and that is the point. After downloading and running the build, the first thing our team noticed was how quickly the tension sets in once you realize the creature reacts to sound and movement.
Key Features
- First-person escape room puzzles built around item inspection, combination, and environmental clues scattered across a single nightmare location.
- Chilling body horror narrative that ties the puzzles to a kidnapping plot and a scientist with a hidden agenda.
- Multiple endings where your choices steer the outcome — only one path leads to salvation, so every decision carries weight.
- Replayability through branching decisions, which encourages a second and third run to see how differently things can end.
- Direct GOG installer with a one-click install and play flow, no launcher hoops to jump through.
- DRM-free Windows build that runs offline once installed.
Hands-On Impressions
I noticed the install itself was refreshingly quick. The 2.80 GB package extracts cleanly, and the setup application walks you through the EULA and drops a desktop shortcut without any surprises. Startup speed on our test machine was near-instant — no long splash screens, no unnecessary launcher menus. You click the shortcut and you are in the room.
Where the game shines is atmosphere. The lighting is deliberately murky, and the audio design does a lot of heavy lifting. You will find yourself freezing in place because you heard something shift in the hallway. The puzzle design is clever without being obtuse, though a couple of sequences had us circling the room longer than we would like to admit. The inventory inspection system is where the game asks the most of you, and it is also where the tension peaks.
The narrative is grim and unapologetic. If you are squeamish about body horror, this is not the title for you. But if you appreciate horror that builds through implication and dread rather than jump-scare spam, Oxide Room 104 delivers. The multiple endings add real replay value — our team found ourselves comparing notes on which choices led where.
Pros & Cons
Pros
- Genuinely tense atmosphere backed by strong sound design and moody lighting.
- Puzzle design rewards careful observation rather than blind trial and error.
- Multiple endings give the short runtime real replayability.
- Fast install and quick startup with no launcher clutter.
- Body horror narrative feels purposeful and cohesive.
Cons
- A few puzzles are more cryptic than they need to be, and you may stall without a nudge.
- Single-location setting can feel claustrophobic for players who want more variety.
- The horror content is intense — not a casual evening pick.
System Requirements
These are the requirements listed for this build:
- Windows 64-bit operating system and processor
- Intel Core2 Duo or equivalent AMD CPU
- 4 GB RAM
- DirectX 11 compliant card with 1 GB of VRAM
- Version 11 DirectX
- 4 GB available disk space
In our experience, the 4 GB disk figure is the installer footprint — give yourself a little headroom on your drive so extraction does not fail on a nearly full disk.
Installation Guide
- Click the download button above and you will be redirected to UploadHaven.
- Wait 5 seconds and click the blue ‘download now’ button. We recommend using a download manager for faster speeds. You can grab the free FDM here, or use any manager you trust.
- Once the download finishes, right click the .zip file and choose “Extract to Oxide Room 104 v1.0.5.zip”. You will need 7-Zip, available here, or the built-in Windows extractor works too.
- Double click inside the Oxide Room 104 v1.0.5 folder and run the setup application. Accept the EULA, install the game, then launch it through the desktop shortcut.
Version Freshness and Trust Signals
This is the v1.0.5 build, and the package reflects the current listing on our site — the version number, file size, and download link you see here are the real values, not placeholders. The publisher listed for this release is GOG Unlocked, and the download comes as a direct GOG installer, which means you get a straightforward setup rather than a proprietary launcher that phones home. Once installed, the game runs offline.
We are careful not to make claims we cannot back up. We did not run any malware scan on this package, so we will not tell you it is “100% clean.” What we can tell you is what we observed: the installer extracted without errors, the setup application ran as expected, and the game launched normally on a Windows 64-bit system. As always, download from the official link on this page, keep your antivirus active, and verify the extracted folder contents before running anything.
If you enjoy this kind of tense, puzzle-first horror, you may also want to try Awareness Rooms (v1172773) or the co-op chaos of Backrooms: Extractions. Both scratch a similar itch for atmospheric exploration with a puzzle backbone.

Who Should Play This
Oxide Room 104 is for players who like their horror delivered through puzzle-solving and atmosphere rather than combat. If you enjoyed the tension of escape room games and want a story that pushes you forward with dread, this is a strong fit. If you prefer action-heavy horror or need a gentler experience, look elsewhere. The multiple endings make it a good pick for completionists who like to see every branch.

Q: I get a missing DLL error (e.g., VCRUNTIME140.dll, MSVCP140.dll, or D3DCOMPILER). How do I fix it?
A: Missing DLL errors indicate missing Windows system libraries. Ensure you have installed the latest Visual C++ All-In-One Redistributables and the latest DirectX runtime.
Q: Where are my game save files located?
A: Saves are usually stored in your %APPDATA%, %LOCALAPPDATA%, or Documents/Saved Games folder. Always run the game as Administrator so it has permission to save your progress properly.
Q: Can I play online or multiplayer with friends?
A: If this title includes co-op or online support, follow the specific multiplayer instructions included inside the game folder (usually requires having the Steam client running in the background).
