# Game engine from one prompt

Grok Bot ran four bots with one coordinator and built a Unity-style game engine from a single prompt, in minutes.

Result: The author got a working Rust editor, .NET 10 scripting, multi-threaded runtime, culling, weather, lighting, water simulation and hot reloading within minutes.

## How it was set up

Four Grok bots were spawned, with the primary bot acting as coordinator. The prompt asked for an engine as easy as Unity without its render pipeline sprawl.

## Worth knowing

Author's own first-impression claim; no repo, demo, or testing of the engine's quality is shared.

## Prompt

```text
Build a game engine with [reference engine]'s ease of use, but without [specific pain points you want avoided].
```

## Evidence note

Author's own description; no repo, video, or screenshots linked
