Vibe coded a multiplayer horde survival game with @threejs and @claudeai Opus 5.5

Here's how I did it in 5 steps.

1. Generate the concept art first
2. Create a build plan and architecture with Opus 5.5
3. Build a prototype and test/iterate until it's right
4. Fill out the entire game with assets using @MeshyAI for 3D and @ElevenLabs for sound effects/audio
5. Deploy multiplayer using @flydotio direct in Claude

That's it.

Game development is about to undergo the biggest shift it has ever seen.

There is no reason why solo devs and tiny studios can't create 10x more games at 10x higher quality now.
