Multiplayer

A multiplayer project can host many users in the same project, either locally or through a networked server. To build a multiplayer game, use a combination of Unity’s multiplayer packages and services. Refer to the Unity multiplayer overview for more information or refer to the additional resources on this page.

If you’re just getting started with multiplayer games, the recommended entry point is the Multiplayer Center package, which suggests Unity multiplayer packages based on the needs of your game, and gives you access to samples and tutorials to help you use them.
