Each week brings a new set of deals on Xbox One games on Microsoft's digital storefront. This week's selection includes big discounts on games published by Microsoft, along with a smattering of other deals. In short, a lot of fantastic games are on sale for up to 75% off, so there's a good chance you can save money on something you've been wanting to play (though some of the discounts require an Xbox Live Gold subscription). Let's take a look at what Xbox One games are on sale between now and September 24.

Most of the killer deals this week are on first-party titles, so now's a great time to pick up any you've missed. The entire core Halo series is on sale, with Halo: The Master Chief Collection ringing in at $22.50 / £15 and Halo 5: Guardians on sale for $15 / £11. If you prefer combat of the tactical variety, you can snag Halo Wars: Definitive Edition for $10 / £8 or the sequel for $20 / £15.
