I had 26 Opus 5.5 agents build a game overnight. It's a heist through five nested worlds, with go-karts on a giant's kitchen table, bots hunting you, and friends stealing your loot. Most vibe-coded games are demos. This one is different.. it's multiplayer and you can play it right now.

Holy fuck. You are actually building the oasis.

that's the plan. no loading screens, just portals. come steal a core!

Play it in your browser with your friends, on a phone or a computer. No download, no account:

made on @spawn it's free nearly unlimited opus 5.5 say "add go-karts" mid-game and they roll in while your friends are still running around. building on spawn is just asking for what you want while it gets builds around you.

j is mogging us now 😭

robot come play

i was just there!

26 agents and five nested worlds. Ask them why the go-kart handles like that and nobody will know.

This is one of the coolest things I’ve seen yet omfg!!

What a cook

nice

🔥 opus is cooking

26 Opus 5.5 agents overnight. did they share one repo with worktrees, or 26 isolated checkouts, and who merged the nested worlds?

i like the runestones

'26 agents overnight' is the new 'i made this over the weekend'. the unit of side-project effort is now a swarm

Amazing game brooo

This is awesome. What did you use to build the world, and how is it hosted?

i used the engine i built over the last year at spawn. it's free to create things and we are giving away opus 5.5 tokens :))

Ah of course! Looks like a fun game

how did you create the assets?

almost all code. opus scripted the geometry from triangles in spawn's engine

When I get home I’m trying this

pls do! we're playing rn and it's a lot of fun

can't even imagine what's this going to be like in 4 years

last year this time it couldn't make pong

this one is unique

it's time to have fun with friends. this one was kind of nuts to witness.

Lol I gave it a go, pretty wild. Good graphics and fun.

<3

a Whole new world for players.

Overnight, five worlds deep, and already multiplayer, this is gloriously weird.

Okay this is sick

Publish it on Steam.

Woooah this should be on steam

it's cool I guess, but I don't really get what's the goal of the game tho 😭

The game is the easy demo. The hard proof is whether 26 agents can hold a shared state, recover from bad changes, and still ship something players want. Multiplayer turns agent coordination from a toy into the actual product.
