Install and upgrade#

To start using the Multiplayer Services package, you need to do the following:

• Make sure you meet all prerequisites.
• Install the Multiplayer Services package.

  Important: If you have already installed one of the Lobby, Matchmaker, Multiplay Hosting or Relay packages, follow the instructions to migrate any UGS SDKs to the Multiplayer Services SDK instead.

Prerequisites#

Before you continue, make sure you meet the following requirements:

• You complete the steps outlined in Get started with UGS.
• You are using a Unity 6 project created with the Universal 3D template to ensure maximum compatibility.

Install the Multiplayer Services package#

To begin a multiplayer project in Unity using the Multiplayer Services SDK, install the Multiplayer Services package:

1. In the Unity Editor's Package Manager, select Unity Registry.
2. Search for Multiplayer Services (or com.unity.services.multiplayer).
3. Select Install.

You can now start using the Multiplayer Services SDK.

Migrate from UGS SDK#

The Multiplayer Services SDK unites the functionality of the standalone SDKs from the following services:

• Lobby
• Matchmaker
• Multiplay Hosting
• Relay

If you're already using any of the SDKs from these individual services in your project but want to move to the unified Multiplayer Services SDK, you must first migrate from the individual services' packages to the Multiplayer Services package. For migration instructions, refer to Migrate to the Multiplayer Services SDK.
