Built with the Guassia game engine.
UNOFFICIAL DOOM SHOWCASE — NO AFFILIATION OR ENDORSEMENT
This is a free experimental browser prototype, provided for testing and solely to showcase what the Guassia engine can do. It is not an official DOOM release.

We did not create or design the original DOOM game. We claim no ownership of its name, trademarks, characters, level designs, artwork, sounds, music, or other original game content. All such rights remain with their respective owners. Our work here is the experimental technical adaptation and presentation using Guassia.
FREE TO PLAY AND TEST. NOT FOR SALE OR RESALE. This hosted prototype is available at no charge for personal, non-commercial play and testing. Do not resell this hosted demonstration, charge for access to it, or package it for sale.

EXPLORE · SOLO OR MULTIPLAYER PRESENCE
Neon Rain
District 09

Shared avatars and movement. NPCs, traffic, targets and scores stay local.
STEALTH HEIST · SINGLE PLAYER
Night Shift
Museum of National Security

Full heist and shorter rehearsal. Personal bests stay in your browser.
FIRST-PERSON SHOOTER · SINGLE PLAYER
Doom
Gaussian Splat Remastered
Play nine solo missions, including Phobos Anomaly and the secret Military Base, in this unofficial Gaussian-splat Doom prototype. Choose from four difficulties and first- or third-person views. Jumping is optional and starts disabled; campaign transitions carry your health, armor, weapons and ammunition.
GPU accelerated rendering is selected by default. Original WebGL is also available on the start screen, alongside High detail, Balanced and Performance graphics presets. Release 0.6 requests mouse capture when you play or resume, and pausing also pauses your run timer.
UNOFFICIAL · FREE TESTING SHOWCASE · NO RESALE.
No affiliation with or endorsement by DOOM’s creators or owners. Original game design and content belong to their respective rights holders. See the full notice above.
TRAINING BETA · GUEST MULTIPLAYER
Mil Sim
Field Lab
Explore on foot, try the tank and helicopter, and meet friends in a shared training room. Switch between forest and desert test areas.
An early development demo with simplified soldiers, vehicles and scenery. Source-model experiments and a graphics stress lab are also available. A desktop browser with WebGPU is recommended.
Before you play
These are early prototypes. A desktop or laptop with a keyboard, mouse and WebGL2 support is recommended. Doom’s GPU accelerated option also needs WebGPU support. If mouse capture is unavailable, use click-and-drag looking where supported, or open the game in its own tab. Touch gameplay and low-end device performance are not yet certified.
Playing Doom? If GPU accelerated cannot start on your browser or device, choose Original WebGL and try again. Allow the models to download and the scene to finish preparing. With Render size set to Auto, Balanced and Performance lower the rendering resolution while retaining the full mission artwork.
Doom community speedruns
Compare the fastest times by mission, difficulty, pistol start or campaign carry, and jumping setting. Results load when you open the board, change a filter, or select Refresh times. Times are community-reported, not anti-cheat verified. Runs from releases before 0.6 may include time spent paused.
