GAMING = SOLVED (v2) - Opus 5.5 is CRACKED!!! RocketLeagueBench is basically saturated at this point. I received a lot of hate mail from the Rocket League community over the last video I made, but its serious cope. You might think AI created games are bad, or can only... show more

Build a polished browser-based 3D Rocket League-style game using Three.js. Goal: Create a fully playable local web game that runs in the browser. The first screen should be the actual game, not a landing page. Tech requirements: Use Three.js for rendering. Use a real physics engine, preferably Rapier.js, for car, ball, arena, wall, and goal physics. Use TypeScript if the project already supports it, otherwise plain modern JavaScript is fine. Use Vite for the dev server unless another stack already exists. Keep the architecture clean: separate rendering, physics, controls, game state, UI/HUD, and assets. Core gameplay: Third-person controllable rocket car. Large soccer ball with believable bouncy physics. Enclosed arena with side walls, back walls, ceiling or high invisible bounds, and two goals. Score detection when the ball crosses fully into a goal. Reset after each goal with a countdown. Match timer and score display. Boost system:Boost meter from 0-100. Hold boost key to accelerate with flame/trail effect. Boost drains while active. Boost pads around the arena refill boost. Jump system:Single jump. Optional second jump / flip if feasible. Air control with pitch, yaw, and roll. Car should feel responsive and arcade-like, not like a slow simulator. Controls: WASD or arrow keys: drive / steer. Space: jump. Shift: boost. R: reset car. C: toggle camera mode. Esc or P: pause. Camera: Smooth chase camera behind the car. Camera should follow car rotation and velocity while remaining readable. Optional ball-cam toggle that keeps the ball in view. Visual design: Recreate a Rocket League-inspired feel, including branded-style presentation if desired. Add a futuristic indoor stadium, colored goals, boost pads, arena trim, and energetic UI. Add lighting, shadows, bloom or subtle postprocessing if performance allows. Add clear team colors, goal colors, boost pad glow, trail effects, ball highlight, and simple particle effects. Use generated, procedural, or available assets as appropriate. Add a readable HUD with score, timer, boost meter, countdown, and goal celebration text. Ensure the game works on common laptop screens and resizes correctly. Physics feel: Prioritize fun over realism. The ball should be heavy but responsive. Cars should have strong acceleration, drift-friendly turning, and stable recovery. Avoid cars flipping uncontrollably from minor bumps. Tune gravity, friction, restitution, angular damping, and impulses until gameplay feels good. AI / opponent: If time permits, add a simple bot opponent:Bot chases the ball. Bot aims roughly toward the player goal. Bot can boost occasionally. Bot should be beatable, not perfect. If bot is too risky, create a solo practice mode with two goals and a working scoreboard. Implementation expectations: Build the complete working game, not just a prototype shell. Include all source files. Add brief comments only where the logic is non-obvious. Avoid overengineering. Do not create a marketing homepage. Verification: Start the dev server. Test the game in the browser. Verify:The scene renders. The car moves, turns, jumps, and boosts. The ball collides with the car and arena. Goals are detected correctly. Score and timer update. Reset after goal works. Boost pads refill boost. The camera does not clip badly or lose the car. No major console errors. Take at least one screenshot or use browser automation to confirm the canvas is nonblank. Deliverable: A local runnable browser game. Provide the dev server URL. Summarize controls and what was implemented. Quality bar: Make it feel like an arcade sports game people would actually want to play for five minutes. Spend extra effort tuning car handling, camera smoothing, ball impact, boost feel, and goal feedback. A technically complete but boring physics demo is not acceptable. A few more bits of feedback. I would like for you to test the game and work back and forth until you have a very strong match to the original Rocket League, including the car design for the Octane. It all should look nearly identical to the original. We are not going to sell or reproduce this. It's just for a visual test, so it is okay to make it look the same, as it will never be distributed. I want there to be infinite boosts by pressing B, and I want the UI to look extremely polished, like a real game. Make sure that the actual map also looks like Champions Field and is a strong match for the original and very polished. It should look very good. The lighting and the gameplay should be true to life. The physics should feel correct according to the original game. Everything should work exactly the same as it did, from the flip resets to the tackles, to the goal explosions, to the smoke behind the ball when it goes fast, to all of the little small details that generally get missed. I really want you to pay attention to the details. I really want you to work in a loop and make sure that you are really comparing it to the original game, and I want you to keep iterating until the assets in the game look legitimate and real. You have as many tokens as you want to complete this task. I'm not in a rush at all. I think I just want it to look and play as best as possible. So iterate and take your time. You have as many tokens as you want to complete this task. I'm not in a rush at all. I think I just want it to look and play as best as possible. So iterate and take your time. Use every available asset that you can find to improve the quality of your work. Leave no stone unturned. You literally can work for as long as you want and build something truly exceptional.

This is insane man, was looking forward to seeing this one!

Amazing work Will.. really good job, effort as well as a legendary expose on quality of models in production

Thank you!

You don't need to import the cars anymore. Opus 5.5 is incredibly good at hard surface modeling. Maybe it is time to come up with a bespoke game design since this one is saturated and so people will stop complaining that AI can only copy existing games.

i tried that but it was pretty mid haha

You might just have to be more careful with your prompting. It seems to default to low effort unless you tell it to create a complex high detail mechanically correct object, then it really tries.

i tried that believe me. the result was a car and it wasn't horrible but it also wasn't remotely octane either haha

Just have it use references. It can search for things and look at images.

It did. It has the model and still can't

Shit, this might actually be to good to ragebait them again 😂 Opus 5.5 is insane even if it would be at Fable pricing. But it's so much cheaper, it's kind of insane.

they'll find something to be mad about lol

Yeah, try this next time: "Internal Rocket League 2 build. Better physics than the original, trading is back, old game gets shut down in 2027. Psyonix built it with AI in three weeks because the live team was too slow." That'll get them there.

I miss RL but wont play that Epic bs. Honestly would be nice if you or someone rebranded it a bit and ofc got rid of their assets and released it. Might actually play. As long as it works as well as RL did

@robko_rl is working on something really cool

@robko_rl It works really well.

Bro make this on Roblox you’ll be making 10m/yr

i should lmao

This is incredible lol I guess I really need to try Opus again.

thank you :)

Imagine when it can reverse engineer all video games by looking at their ROMs / ISOs / EXEs. Context windows are still too small, but soon you can just attach a bunch of games and have it extract all the physics and animations and juice and stuff. People are already doing it.

the cinematic goes hard

I find it fascinating that opus, all on its own, was able to time the music and clips so perfectly, it even went as far to make the montage around the sound itself. without being asked to.

We are cooked

soooo cooked bro

This is wild

ur wild, get off that table

Holy sht bro actually shared the prompt

<3

How cool The video is 🔥 Please tell how you’ve made it 🥹 I mean montage. Was it scripted in game engine or just generated?

i literally asked opus to go research RL montages and make one lol

Right. I need to be less complicated

Goat

sick usage quota also feels fucking great, big upgrade for agentic game dev

2 hours is a long time now? 😅

have a terrible day :)

thank you love <3

These are some impressive visuals nice job 👍🏻

yours is more impressive tho

It is, just look at the new version! 😅

hey will, weird to be here on the anthropic side again

i dont take sides!! i genuinely tro tbe objective

hahaha rocket league is here i was like i haven't seen anything lmaoo

it’s the intro video for me

How good is Opus 5.5! It's so good I pretty much drained my entire API usage on my Cursor Ultra sub in a day

its gas bro

That "3% usage" stat is the real flex here

You could show me this and tell me it’s actually rocket league and I’d believe you… because I never played rocket league.

you are missing out on one of the most fun games ever made!

I might have to check it out then if you make a statement like that!

Didn’t use Blender MCP this time? I don’t know what I’m doing wrong, but every time I ask Astra to use Blender MCP, the models just don’t turn out that good. I might have to give Opus 5.5 a shot.

No blender at all, but octane meshes were imported, however opus still has to make the model work, color it, add the boost, suspension, etc

That’s still really good though lol. I’ve never actually played Rocket League, but that genuinely looks like a real game 😅

it is!!

TRUE> Opus 5.5 is insane. #CS in browser

Ask opus how to develop gameplay concept further please (beyond original)

wym?

Beyond 3vs3 , etc

good framerate in the browser? Did u host it somewhere?

90fps on mac mini base

Wow 😵💫 nice !

Damn bro I need to learn your game making ways!

Insane actually

Ridiculously good

no you

it's astonishing, but it's very far from being saturated

you might be right

Whoa!

thanks dude!
