MYCELIUM ENGINE — MARKETING COPY
Brand direction: Night Garden
Prepared: 2026-10-02

TAGLINE
Small core. Wild possibilities.

SHORT DESCRIPTION
Mycelium is a modular, native engine for games and interactive software: C# with a Native AOT player, an editor AI agents can drive, and a UI built for apps. Built on .NET 10, it connects scenes, UI, state machines, and scripts through a shared core—with efficiency as a design value. Currently in alpha.

LAUNCH POST
Small core. Wild possibilities. Meet Mycelium: a modular, native engine for people making games and interactive software. Start with an example, connect the pieces, and see what grows. Built on .NET 10. Open source. Currently in alpha.

TECHNICAL BOILERPLATE
Mycelium Engine is a modular .NET 10 engine and editor for games and applications. C# scripts publish with a Native AOT player, every editor command is a typed tool an AI agent can call through MCP, and its themeable UI stack is built for applications. It draws 2D, and 3D in preview: PBR meshes with sun shadows, sculpted terrain with grass, trees and water, and endless terrain worlds. Its native pipeline brings together scenes, state machines, a shared blackboard, and an observable command system. Vulkan is the primary renderer, with OpenGL as a compatibility backend. Optional modules, allocation discipline, idle frame pacing, and battery-aware behavior support an efficiency-first approach. Desktop is the primary target, with mobile workflows developing. Mycelium is alpha software; consult the roadmap for feature maturity and current limitations.

CAMPAIGN LINES
Start small. See what grows.
Make more. Ask less of the machine.
A small core. A living network.
