Inside the Survival Kids Multiplayer Network Architecture
Unity Studio Productions developed Survival Kids as a day-one Nintendo Switch 2 launch title using Unity 6 and Netcode for Entities. The team created a unified network architecture supporting single-player, local co-op, online multiplayer, and GameShare functionality. They used Unity Relay for cloud hosting and maintained a single codebase for all play modes by treating single-player as a networked game with in-process connections. The biggest challenge was optimizing performance to run both server and client simulation simultaneously while maintaining 60 FPS.
