The next Xbox One update promises to focus on multiplayer and party improvements and as of today Xbox will begin sending invites out to allow early access to selected Xbox Live members.
Previous Xbox 360 updates have required Live members to sign up in order to gain early access to any update, but with the Xbox One, things are seemingly going to work slightly different.
There is no signup process but instead Xbox will send selected participants a message over Xbox Live with a code to register. Once registered, members will be able to test the early features as soon as next week and will be asked to provide feedback in a private forum.
Have you received an invite? Or will you have to wait until the update goes live properly some time in March?
