Omnipresent Xbox spokesman Larry "Major Nelson" Hryb unveiled the offer on his blog earlier today. "Starting at select retailers next week in the U.S., a digital copy of Forza Motorsport 5 will be included with purchases of Xbox One for the retail price of $499.99 for a limited time," Hryb wrote, before launching into a hyperbolic, if not inaccurate description of the racer. Our own review of the game awarded it four of five stars, with Ludwig praising the game's functionality and attention to detail, but lamenting its anemic selection of vehicles and tracks - an issue that has since been partially amended by DLC additions.
Unfortunately, according to Microsoft, this promotion does not apply to Xbox One consoles purchased as part of the upcoming Titanfall bundle.
