Unity Multiplayer Services provides a comprehensive framework for building multiplayer games, offering solutions for networking, server hosting, and player connections.

The Multiplayer Services (MPS) SDK unifies Lobby, Matchmaker, and Relay under a single, cohesive API, replacing their individual SDKs. This consolidated approach reduces development complexity while maintaining the full capabilities of Unity's multiplayer infrastructure.

Note

Existing games already using Lobby, Matchmaker, or Relay can be upgraded to the Multiplayer Services SDK by following the upgrade guide.

The MPS SDK introduces sessions, which isn't a standalone service but instead an abstraction layer that manages how players connect and interact in multiplayer games. Sessions handle the complexities of player grouping, connection management, and game state coordination, streamlining the development of both peer-to-peer games and dedicated server experiences.
