Similar to the Game Preview Program, the Xbox Insider program allows users to test games with early updates, and give feedback on their experiences.
The Xbox Insider Program is how to give feedback on what's new, before anyone else. Whether you're testing new system features, or trying a new game or app, you can use the Xbox Insider Hub to let developers know what you like and what you don't via quests, surveys, report problems, and more.
On this page, you'll find a full list of titles published through the Xbox Insider program.
