Network

Works anywhere

All games use rollback netcode — the system predicts inputs and corrects on the fly so you don't feel lag. Under 60ms feels like local play. Works over LAN or across the internet — game traffic routes through a US East Coast relay server, so no port forwarding or VPN is needed.
