Rolling out to Xbox Preview members this week — alongside Xbox Arena, looking for group posts and group messaging — is a whole new sound and icon to accompany rare achievements. Give it a listen. The melodic Xbox achievement knock is an iconic gaming sound, and it will still be there for run-of-the-mill achievements. But special, rare achievements are getting a special, epic version of the sound and a diamond icon to match. Check it out in the video below from Xbox's Major Nelson via The Verge.)
Here it is without all the Forza-ing.
Really gonna feel those once they go live later this year.
Preview users are also getting a chance to participate in daily Killer Instinct tournaments via the new Arena functionality, create LFG posts for future gaming sessions and message with multiple friends at once. All of these changes will be rolling out to all Xbox One users later this year.
