Someone ran Opus 5 for 12 hours straight on Ultracode with a multi-agent loop. It built a full 3D Pokémon game. Pallet Town. Explorable. A complete game that would have taken a small team weeks. Built overnight by one person who went to sleep and woke up to a... show more

THIS SOLO DEV IS BUILDING A 2.5D MEDIEVAL SWORD FIGHTING GAME AND THE COMBAT LOOKS INSANE one person working alone on a full combat system with 2.5D art style he designed and built the art, environments, and animations himself. vibe coded the game mechanics with a game engine the silhouette work and the environments already look polished. the characters move through these detailed medieval landscapes with real weight to the animations 2.5D means the characters and world are flat sprites but rendered in a 3D space so you get depth, parallax, and lighting effects without needing a full 3D engine the combat has directional attacks, parrying, and what looks like a stamina based system. all built by one person i think it needs a bit more hit feedback like hit-stop and sharper audio on contact to make every swing feel heavier. small tweaks that would take it from looking good to feeling incredible but nonetheless this looks pretty slick. insane what one person can do now with vibe coding + a game engine solo game devs are building things that would have required a full studio 5 years ago

I built an autonomous 3D Python Game Visulizer Agent team with browser use and DeepSeek R1. It has 4 AI agents working as a team to open, code, run, and visualize the game in the browser - all on autopilot. 100% Opensource code with step-by-step tutorial.

This guy just built a full procedural world generator with real time Unreal Engine rendering using Fable 5 in literally a couple of hours. Not some basic demo, proper landscapes, lighting, and details that look straight out of a AAA game.I can't even imagine how many tokens he burned through, probably enough to power a small country for a day This is straight up insane. One guy with a strong model doing what used to take big teams months or years. We're actually watching the game industry get completely flipped upside down in real time. Mind officially blown.

Does it bother you that sequel to your one of the favorite games is being built on Unreal Engine 5? Would Witcher 4 - a huge open world game be limited by UE5 performances?

Lot's of noise recently about Gauntlet Loop after Matt Shumer game example - but truth is most agent loops without standardised frameworks around game libraries, 3D models, textures, terrain, lighting and multiplayer turn out to be super unpredictable, messy, overly expensive, as @levelsio pointed out Today we're introducing LOOP - our take on agent loops to build AI games. The Tesana LOOP inside our AI game engine solves assets → game libraries → multiplayer → and a full user-facing experience. Set a budget for your LOOP, and come back to a properly finished game ready to launch, without reinventing and wasting tokens on your build every session.

Someone built a full 3D video game with ChatGPT 5.5 and a single prompt, no unity, no game dev degree, no team. Not a prototype or demo, this is a full 3D browser game: low‑poly mountains, interactive bubble mechanics, smooth camera, and a complete UI, running on a laptop. For context, Rockstar has 2,000 engineers and takes 10 years between GTA releases. Indie devs spend 3 years learning Unity before they ship their first game, game dev bootcamps charge $15,000 to teach you enough to get started. This guy typed a prompt -> 10 minutes later the game was running. No engine, no language, no course, no team, no budget, no timeline, no publisher taking 30% of something that took 3 years to build. Just an idea, a prompt and ChatGPT 5.5 handling everything else. The gap between having a game idea and shipping one just went from 3 years to 10 minutes.

I built a bot on an ESP32 that can create full projects by itself. Ask it to generate images, videos, 3D, build a website and publish it, it does everything autonomously. Powered by Claude Opus 4.6 for code, visual content generated with fal, bot powered via OpenClaw🦞 The skills to generate project with fal are here All running on a tiny M5Stack Core2.

One team spent 3 hours per Roblox UGC item. I built them pipeline that does it in under 5 minutes, reference image to published, hands-off. Watch the whole run in 48 seconds 👇 Generated with Roblox new Cube 3D, then fitted, thumbnailed, titled, validated, and auto-fixed by a Claude skill and a Studio plugin I built. Reference image to live on the Marketplace, hands-off. Need rapid tooling like this or a 7-day game prototype? I'm taking on a couple of projects. DMs open.

Claude Opus 5 built a Red Dead Redemption-style open world western in Three.js with just a few extra prompts added to a gauntlet loop. The result is a surprisingly strong environment with horseback traversal, large-scale terrain, atmospheric lighting, and a level of polish that already looks better than a lot of small indie prototypes. Play it: Repository: Project by: Michael Gill

Thanks to leaks, we now know Pokémon Project Synapse – a new online multiplayer Pokémon game is being unveiled this week. But what is Pokémon Synapse? The short answer is we don't know yet, we know it's multiplayer and likely being developed by Pokémon Works, the new company set by ILCA and TPC, but we have some hints about it from last year's Teraleak. In the Teraleak there was another game that fit this description - the cancelled Pokémon Project Rodeo. The game is also an online multiplayer game for both Switch and smartphones and revolves around using ride Pokémon to defeat rampaging Pokémon. In the pitch document for it, it mentions some Splatoon references for the fact that you can customize your characters and your gun (yeah it has some kind of gun), and the fact that it's a team based online game. While Rodeo was cancelled, we think that parts of it have been reincorporated into Synapse, what we don't know yet is how different it is now.

CookieRun: New World brings the franchise into a new era with open-world gameplay, arriving on Mobile, PC, and Consoles in 2029. This game from Devsisters really nails it with its Cookie characters, Pokémon-like creatures, vibrant open-world, and everything in between. Built using Unreal Engine, this is one of the two projects they previously teased as Project N, along with Project CC. 🔗

So here it is, my new mod Project Trailer for Pokémon Legends Z-A What do you guys think? HD: Also what I would to ask to the community if theres Pokémon we dont have dub for them, would any of you guys like to dub any Pokémon in the Game for the mod? Think this will be a free mod at the end and there will be the credits for every people that voiced a Pokémon. So if you guys are interested on contributing Feel Free to DM me and ill try to setup a discord server to start developing more the project.

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.

I've been working on web projects with Three.js more and more lately — 2D, 3D, XR — and the one thing I've noticed is the lack of tools compared to game engines. That's why I decided to start building on the side a library of 3D assets that are actually little programs, AI-native, and fully customizable. I called this Polyfork , and it's already being used by dozens of people that have an AI centric workflow, since the website can be fully understood and used by agents. Assets are being built each day, at a rate of 100+ a week, and I'm planning to make it the biggest programmatic-3D library on the internet. Almost half of the models are free, and I opened slots for "founding" members, who can make a one-time payment for lifetime access, with access to all current models and kits, plus everything built from now on. Get one before they run out.

Last year I built a full Unity VR/MR demo for our talk and the Meta booth, and it took me around 3–4 weeks to complete. This year, with only a week left before GDC, I was definitely feeling the pressure. Surprisingly, I ended up building a full VR game with AI in just one day. The tech stack 👇
