Want to build a real multiplayer game—not just a local demo? In this comprehensive tutorial, we'll create a complete Space War multiplayer game using Unity 6, Netcode for GameObjects, and Unity Gaming Services (UGS). We'll leverage the Midnite Oil Software Multiplayer Boilerplate to skip the tedious setup and focus on what makes your game unique: the gameplay!
Learn how to architect a scalable multiplayer system, synchronize physics-based space combat, handle player connections gracefully, and deploy your game to the web with WebGL and itch.io.

WHAT YOU WILL LEARN
- Package Installation: Setting up the Midnite Oil Software Core and Multiplayer packages for Unity 6.
- Multiplayer Play Mode (MPPM): Testing multiplayer locally without building multiple instances.
- Architecture Deep Dive: Understanding the server-authoritative multiplayer architecture and event-driven design.
- Game Implementation: Building the complete Space War game including fighters, projectiles, gravity wells, and UI.
- Physics Synchronization: Handling networked physics with Rigidbody2D and screen wrapping.
- Interface Design: Creating reusable gameplay interfaces like IDestroyable for clean architecture.
- Debugging Multiplayer: Real-world troubleshooting of networking issues and client synchronization.
- WebGL Deployment: Building and deploying your multiplayer game to itch.io for browser play.
