IZT-92 is a multiplayer sci-fi arena demo built in Unity, showcasing Firebase integration for authentication and persistence alongside Netcode for GameObjects for real-time synchronization. Players join stylized 2D arenas as colored squares, progressing through authentication, matchmaking, lobby staging, and live gameplay with server-authoritative movement. Featuring a glass-inspired UI aesthetic, structured scene flow, and robust Relay-based networking, IZT-92 serves as a template for high-performance networked applications with authenticated sessions, matchmaking, and persistent data handling.
