Multiplayer

A House is the pre-match coordination context. The listen server (LS), dedicated server (DS), and backend have different responsibilities throughout its lifecycle.

Start with the House lifecycle map for selection, freeze, admission, deployment, and travel. It connects the Unreal lifecycle to the focused backend launch protocol.

For the return journey, consult the rehost section and UI rehost debugging notes. These legacy pages need verification against current code before being treated as current contracts.

Backend-wide formats and integrations are mapped in Backend.
