Over the weekend, Chart-Track announced their list for the UK's best selling video games for last week.
Topping the charts at number one was Quantum Break which beat Dirt Rally (developed by Codemasters). Both games were launched last week.
Following the announcement, Microsoft added that QB is currently "Microsoft Studio's best-selling new IP of this generation" as well as it being the "best selling boxed game" in the UK last week.
At present, it's unknown how many copies of the game has been sold on either XBOX One or Windows 10.
