## What it is
Megacity Metro is an open-source multiplayer shooter game sample from Unity built with DOTS (Entity Component System) and Netcode for Entities, supporting 150+ players per session with server-authoritative gameplay. It integrates Unity Gaming Services for game server hosting, matchmaking, and Vivox voice chat, and serves as a large-scale multiplayer demo and learning resource.

## Use cases
- learn how to build large-scale multiplayer games with Unity DOTS
- study server-authoritative netcode with prediction and lag compensation
- see how to integrate Unity Gaming Services like matchmaking and Vivox voice chat
- benchmark ECS rendering and streaming performance with 150 players
- use as a starting template for a Unity multiplayer shooter
- explore Unity 6 rendering features like Render Graph and STP

## When to choose
- you want a production-quality reference for Netcode for Entities and DOTS
- you are building a large-scale multiplayer Unity game and need architectural examples
- you want to evaluate Unity Gaming Services integration in a real project

## When to avoid
- you need a small, lightweight starter template - this is a large project with long build times
- you are not using Unity or DOTS
- you need a fully supported game engine rather than a demo/sample project
