SOMEONE MADE A FULL GAME WITH CLAUDE CODE, THE ART, THE ANIMATIONS, THE MECHANICS, EVEN THE TRAILER most vibe coded games pull free sprites off the internet or generate images, but this guy had claude design every single asset from scratch, art, sound, animation, cutscenes, all of it > its a 2d pixel art roguelike where you play as a little slime slingshotting knives at ghosts, going deeper into an increasingly violent world > you move around top down, fight enemies, take damage, collect loot, it plays like a real game not a demo > its a revival of a game he originally made back in middle school > claude designed every asset, and the sprites are generated in code, not image files > the entire trailer was made by claude too, he didnt touch the process at all > he ran hundreds of claude terminals in parallel to split the workload across fable agents, because generating that many sprites eats context fast he steered the general game design and feel, then let claude do the heavy lifting on everything else the reason most of these games look identical is everyone is pulling from the same asset packs but when the art is written instead of downloaded, it actually has its own style

It’s incredible that you can let Opus 5 run for two hours in Claude Code and get a cinematic Three.js movie inside one HTML file. It created the story, scenes, transitions, camera moves, and procedural world. Higgsfield generated the narration, sound effects, and music. I mostly helped with references for more realistic grass, added the skills I use, and asked it to keep verifying its work. It’s all open source, so you can play with the code.

opus 5.5 extra high "create a new project in my projects folder called "endless-game": an endless, procedurally generated world built with three.js in the browser that i can roam freely and just enjoy. every area should be randomly generated, with surprises everywhere no matter how long i play. it should feel calm, relaxing and genuinely fun, like the cozy, satisfying vibe of a supermarket simulator, but it shouldn't be a supermarket game. i want a really interesting world to walk around in, with entities i can meet and interact with, and really cool graphics. set a clear goal for the project, keep working until you reach it, and play a sound chime when it's done and ready for me to play and test."

I wanted to quickly create a short video with Opus 5.5 about the history of AI, from "Attention is all you need" to AGI. No stock footage, no image or video generators: every frame is rendered from code. This 3-minute film was made 100% in code by Claude in Claude Code: ~7,400 lines of React/TypeScript (Remotion), every image drawn in SVG and Canvas, an open-source TTS voice, and a score synthesized in Python. No stock footage. No image generators. Id say pretty cool! Tookl about 1h and 7% weekly rates.

This first-person shooter was built from a single prompt, using 404-generated 3D assets. On the latest Novelty Search, 404 explains how SN17 is moving from Titan, its open image-to-3D model built with miners, toward 3D assets generated as code that AI agents can edit and use directly in games. That work is part of a broader direction for 404: building world models where AI agents can learn and act. Hosted by const Full episode in the first comment

Someone on Reddit just built a AAA-quality snow simulation in their browser. Using Claude Opus 5. Millions of snow particles. A character in a robe with cloth physics. Five water-based spells that carve the terrain. A snow surfing system with a wake that throws spray into sunlight. Every footstep displaces snow. Trails form berms at the edges. Trenches slowly refill over time. Spells leave permanent craters. The entire thing runs in one browser tab. WebGPU. No game engine. No 3D modeling software. Just code. He wrote one detailed prompt. Opus 5 planned the architecture, wrote the shaders, built the physics, iterated from screenshots, and documented every decision. 9 hours. ~4 million tokens. You can open it right now and walk around in it. This isn't a demo. This is the kind of thing a small studio would spend months building.

Another impressive and early Claude Mythos output for y'all. 😀 I literally just told it to generate a macOS clone and to do its absolute best. It generated 50k tokens (3k lines of code), made a fully functional browser, made a music player with generated songs and added a lot of sneaky witty details. AND this is also LOW effort!
