4Players ODIN

Our Unity SDK offers a quick “go to market” solution for immersive 3D voice chat that you can just “drag & drop” into your game or XR experience. ODIN is deeply integrated into Unity and handles all communication with servers and provides easy to use delegates and events that allows you to customize the experience very easily to your own needs.

Source Code

You can find the full source code to our Unity SDK in our public GitHub repository:

If you encounter any bugs or issues, please let us know in the GitHub Issues area or refer to the Support page to contact us directly.

Getting Started

If you want to learn more about 4Players ODIN and how it fits into your game or XR experience then follow the Introduction. We have compiled a couple of use-cases for different types of games that should get you started quickly.

Follow our Getting Started guide and implement ODIN into an empty project in less than 20 minutes and learn about the basic concepts. Implementing ODIN into your multiplayer project is very easy too. Check out our Multiplayer Guide that will guide you step by step building a very easy multiplayer game from scratch with 3D voice chat support in under an hour.

Installing the SDK

Please follow these steps to install our SDK into your Unity project:

4Players ODIN supports Unity 2019.4 or any later version. The latest version is always available in our Github repository or in the Unity Asset Store.

There are numerous ways to install ODIN into your project. We recommend using Package Manager.

Install via Asset Store


4Players ODIN package has been in the asset store for many months and has been updated every week and passed the approval process numerous times. But suddenly Unity pulled our package from the asset store claiming that we have to be part of their Verified Partner Solutions program. We are in the process to get that resolved, but in the meantime you need to install ODIN using the Package Manager manually. Sorry for the inconvenience. Please contact our support if you have any issues with the installation.

Install via Unity Package

Please download the latest version of the ODIN Unity SDK as a .unitypackage from the [Github releases page] ( Just double-click the .unitypackage to import it into your current Unity editor project.

Package Manager

Using the Package Manager will ensure that all dependencies are set up correctly and that you will have the most up to date version of the SDK. In most cases, using the Package Manager is the way to go.

To open the Package Manager, navigate to Window and then click Package Manager in your Unity Editor menu bar.
