# Local testing via Unity's Multiplayer Play Mode

[Multiplayer Play Mode](https://docs-multiplayer.unity3d.com/mppm/current/about/) (MMPM) is Unity's official solution for local multiplayer testing, available from Unity 6.

**Pros**

* Short iteration times
* Tighter integration within the Editor, doesn't require multiple (standalone) Editors open

**Cons**

* Requires Unity 6+
* Can be more resource demanding than just running builds

## How to use?

* Install MPPM as described in their [Installation Instructions](https://docs-multiplayer.unity3d.com/mppm/current/install/)
* Open *Window* > *Multiplayer Play Mode*
* Enable up to 4 virtual Players
* Make sure that the [baked data](/manual/baking-and-code-generation.md) is up-to-date before starting to test, and that the Replication Server [is running](/getting-started/setup-a-project/test-in-the-cloud/deploy-replication-server.md) with the latest schema
* Enter **Play Mode**

**coherence** tells apart virtual Players from the main Editor, so it's easier for you to not edit assets in clones by mistake.
