Opus 5.5 should be illegal. But it's not, so, WHEEEEE!

[Andres Chilkowski @Chilkus]

I gave myself one week of my spare time to see what a game designer with 30 years of experience, but no coding skills, could build using AI.

The result is Marble Marvell, an unofficial and non commercial, free tribute to Marble Madness.

Made in admiration of @cerny, a personal idol, and Bob Flanagan, who made the original 42 years ago.

Why is working on this so good? I can't stop🙁

This was ONE image. Now you can walk into it. ❄️

Not just the cabin. Not just the character. The whole scene.

Hyper3D × img2threejs × Three.js × GPT-6 Luna

The workflow starts with a picture of a world.

img2threejs analyzes what’s inside: the house, trees, rocks, character, and their arrangement.

Hyper3D provides the 3D references. GPT-6 works through the img2threejs pipeline to reconstruct the objects and bring them together in Three.js, rebuilding the scene with depth, lighting, and interactions.

But recreating the picture is only the beginning.

Walk around the cabin and leave footprints in the snow. Open the gate. Turn day into night. Place a campfire and watch the world take on a different atmosphere.

You’re no longer limited to the moment or camera angle captured in the original image.

This isn’t just making a picture move.
It’s rebuilding what’s inside it into a world you can explore, edit, and keep building.

One image sets the scene.
You decide what happens next.

Fallout: New York, a full Fallout game you play in your browser, built with Claude Opus 5.5.

Quests. Dialogue trees. V.A.T.S. A working Pip-Boy.

Zero texture files. Zero sound files. Every building, weapon, face and sound is generated by code.

Sonnet 5.5, the Fortnite test.

I was NOT ready for it to one-shot something this close to the real game. 🤯🔥

[Timothée Le Borgne @Tim_LB]

PEOPLE, IT'S TIME.

Opus 5.5 vs Sonnet 5.5 on my TinyWorld Benchmark.

I am BLOWN AWAY.

Sonnet 5.5 is almost at the level of Opus for... 20% of Opus' cost, and it's WAY faster.

$0.96 vs $4.79
10.8min vs 22.7min

Well done @AnthropicAI !

The game I built yesterday with 1 prompt got 4,500 plays & 360k views in less than 1 day. Using Opus 5.5 & @threejs on @TesanaAI.

So I decided to keep building on it. For my second prompt I added dynamic & seamless space battles. Jump into your spaceship, fly out of the atmosphere and straight into a galactic war with massive juggernaut ships.

Dog fight through the battle, then leave the fight and seamlessly fly back down to the planet and keep exploring.

And this is the power of Tesana. You can create something like this in an hour and then just keep building on top of it. Add whatever you want.

New planets, enemies, weapons, quests, mechanics, entire systems. Or make it a space pirate game?

You can basically start with an idea and keep turning it into whatever game you want without knowing how to code.

[Tiger Abrodi @TAbrodi]

opus 5.5 built this game with me in 2 days.

now my friends and i can't stop playing it.

Claude Sonnet 5.5 is getting REALLY good at building games.

A 40v40 shooter with airstrikes, built with Higgsfield.

League players, DOTA players, HoTS players. I need you in the same lobby for a minute.

I just got Opus 5.5 to build a 3rd person MOBA, then added heroes from all three games.

Li-Ming and LeBlanc are both playable. So are Rubick, Axe, Thrall, Stitches, Kael'thas, Thresh and Ezreal. Full action combat: dodge roll, double jump, jump over projectiles.

Which hero goes in next? It's live below 👇
