By the end of this chapter, you'll learn to:

Understand how multiplayer games actually work under the hood, the four systems every online game needs (identity, persistence, real-time sync, and server authority).
See why SpacetimeDB is a fundamentally different approach: instead of stitching together a web server, a database, a WebSocket layer, and an auth system, you write one Rust module.
Set up SpacetimeDB locally, publish your first server module.
Implement the server side: a player table that stores who exists in your world, and reducers that automatically handle players joining, leaving, and coming back.
Connect your Bevy game to the server so that clicking Multiplayer opens a live connection screen showing your player name and who else is currently online.
Run two instances of your game side by side and watch them recognize each other as separate players on the same shared server.
