Just a few days ago, a leaked screenshot showed the Halo 3: ODST addon for the Master Chief Collection was being released on Friday, May 29th. Microsoft responded to the leak, saying it was an incorrect listing, and that it would provide the details when the time to launch had come. That time came much faster than we were expecting.
I received an Xbox Live message early this morning containing my code to redeem ODST, just 2 hours shy of Microsoft’s original leaked release date.
ODST is nowhere to be found on the Xbox store, and there’s been no word from Microsoft about the matter, but we’ll be sure to update you when they comment on it.
