The company appears to be doling out a free extra game code to select owners of the new system. In the reports that we've seen, the game is a digital copy of Ryse: Son of Rome and we've not seen any reports from outside of the United States as yet.

We just thought we'd post it to remind you to check your messages often - you never know what could be inside!
