NOCLIP
First-person surreal horror in the Backrooms, where your camcorder sees the doors, marks and monster you can't.

What it is
You were closing up the furniture store when you found a wall in the back outlined in duct tape, and you walked through it. Now there is carpet that never dries, a hum that never stops, and fluorescent light falling on rooms nobody built. Every place down here is a copy of a real place, dubbed from a dub until the details slip: doors with no handles, signs that almost read, rooms bigger inside than out. Your camcorder shows what the place really is, including the thing that hunts the halls by sound. You will die often; your tapes sell for salvage at a company post near the entrance, you buy a flashbulb, flares and quieter shoes, and you take the stairwells deeper, where the copy gets worse.
Screenshots
All stills and clips come from the game's own capture harness: an autoplay bot on a random seed, nothing hand-posed.
How it was made
- Engine: Godot 4.7 (Forward+, GDScript) with realtime global illumination, volumetric fog and area lights. It won a blind look bake-off against three.js WebGPU in the first session.
- Procedural and seeded: Level 0 streams in chunks built from a seed (rooms, highways, loops, splices), so one seed rebuilds a level exactly. Impossible spaces include rooms bigger inside and doors the camcorder reveals in solid walls.
- Assets by script: Blender runs headless for every model fix-up and export; props are CC BY models from Sketchfab, rescaled and re-exported (credited below). The creature was concepted with Gemini, modeled and rigged through Meshy, and picked by a blind panel of AI judges. Sound effects and ambience were generated with ElevenLabs. Every generated asset has its prompt and parameters recorded under
pipeline/manifests/.
- Blind review loop: each session a capture tool records stills, motion contact sheets and a two minute video with audio, then two critics who never see the code (Claude on stills, Gemini on the video and sound) score it like players. 31 rounds so far, logged in
review/scores.csv and review/critiques/, with every complaint triaged in review/LEDGER.md.
- Built by: Claude (Anthropic) as lead developer across seven sessions from October 1 to 3, 2026, with Stewart directing and play-testing. The progress pictures in
progress/ show the whole history, one dated image at a time.
