Warning
We are winding down our direct support for the Unity Multiplay Game Server Hosting Service. Unity will support the Multiplay Game Server Hosting Service through March 31, 2026. To ensure continuity for live titles, we are licensing our Multiplay Game Server Hosting software to Rocket Science Group. Learn more about them here.
Multiplay Hosting automatically uses differential updates to distribute your build updates efficiently. A differential update (also known as a partial or delta update) is an update that has only the differences between the earlier build version and the new build version. Differential updates are helpful when you want to update a build as fast as possible. Because they contain less data than full updates, Multiplay Hosting can distribute the differential build across your fleet faster than a full update.
Tip
It's best practice to use the same build machine to create new build versions to reduce the possible changes between builds. You might consider using a build server, such as Build Automation.
