## What it is
Ambient is an open-source cross-platform runtime and multiplayer game engine built with Rust, WebAssembly, and WebGPU, featuring an in-game ECS database, automatic network synchronization, and WASM-powered package isolation. Development on the runtime is paused indefinitely as of the project's warning notice.

## Use cases
- build a multiplayer 3D game in Rust
- deploy and share web-based multiplayer games
- create games with automatic client-server state synchronization
- run sandboxed WASM game packages
- prototype 3D games with PBR rendering

## When to choose
- you want a Rust-based multiplayer game engine with built-in networking and ECS
- you need cross-platform deployment to web and desktop via WASM/WebGPU
- you want sandboxed, interoperable game packages

## When to avoid
- you need a maintained engine with active development and support
- you require a large ecosystem of assets, plugins, and community resources
- you are starting a new long-term project, since work on Ambient is paused indefinitely
