Meshy Labs unveils first game with AI-generated mechanics at runtime
Meshy announced a new experimental division called Meshy Labs at GDC 2026, along with its first game: Black Box: Infinite Arsenal. It's a survivor-roguelike where the gameplay mechanics themselves are generated by AI at runtime. Not the assets. The actual weapon physics, elemental effects, trajectories, and damage parameters.

How it works
Players type text prompts to describe the weapons they want. A "Designer Agent" takes those prompts and assembles atomic mechanics into playable weapons in real time. There's no fixed weapon database, no preset loadouts, and no hardcoded builds. Every run produces unique gameplay based on what the player asks for and how the AI interprets it.
The result is that two players can play the same level and have completely different experiences. One might describe an "ice beam that bounces off walls" and get exactly that. Another might type "gravity hammer that pulls enemies in" and get a different set of physics entirely.
What Meshy is framing
CEO Ethan Hu positioned this as a shift from "AI for 3D" (which is what Meshy is known for) to "AI for Fun." The idea is that AI shouldn't just speed up asset creation. It should become part of the gameplay loop itself, where players co-create the experience.
That's a big claim. Whether it works at scale depends on how well the Designer Agent handles edge cases, balances difficulty, and avoids generating broken or unplayable weapons. A demo was playable at GDC booth #941, and the game is listed on Steam as coming soon.
Business milestones
The numbers behind the announcement are significant. Meshy doubled its annual recurring revenue to $30M in just three months. The platform has passed 10 million users globally. The company also released Meshy-6, its latest generative model, which features improved geometry for both organic and hard-surface models and a new low-poly generation mode.

Why it matters for game developers
Most AI-in-games conversations focus on asset pipelines: generating textures, 3D models, dialogue, or level layouts. Black Box: Infinite Arsenal is the first public example of AI generating the mechanics themselves. If the approach works, it could open a new design space where gameplay emerges from player intent rather than developer-authored systems.
It's early. But the fact that a company with $30M ARR and 10 million users is putting resources behind this makes it worth watching.
