Microsoft on Friday announced a limited-time promotion where consumers will be able to get a free Xbox One game with the purchase of a new console. The promotion starts this Sunday, June 21, and runs through June 27. It is valid in the United States only at participating retailers.

During the promotional period, everyone who buys an Xbox One–all 500GB and 1TB models–will get to choose any free Xbox One game. You can actually get an extra “free” game if you buy one of the various Xbox One bundles that comes with Halo: The Master Chief Collection, including the new 1TB model.

The only notable limitation for the offer is that it’s not good on preorder games. It’a also worth noting that your free game will be for a disc-based title, not a digital one. As always, you should speak with your local retailer for further specifics about the promo.

Last year, Microsoft offered a very similar offer.

At E3 2015 this week, Xbox executive Aaron Greenberg predicted that a string of exclusive games and new features like backward compatibility will lead to a “massive” surge in Xbox One sales this holiday.
