Recent testers for the New Xbox One Experience should be checking their inbox. Microsoft has given their thanks in the form of a special digital present: a ninja cat accessory to go with your avatar on Xbox Live.
The cat is quite animated and will even play games with your avatar. This gift goes along with a recent update that provides additional content for avatars, showing that Microsoft intends to continue supporting the feature in spite of some users distaste for it.
If you were a tester, head over to your Live account to check your messages; your reward should come in the form of a message from Microsoft along with a download link.
