Xbox One users will be able to play 104 Xbox 360 games (assuming they already own them) from 8pm tonight (12 November) as Microsoft rolls out the new, Windows 10-powered Xbox One dashboard globally.
Updating your console with the new look, vastly-improved dashboard won't automatically trigger backwards compatibility, which was announced back at E3 to the shock of the industry. Instead it's triggering at the set time, 8:01pm GMT (9:01pm CET, 3:01pm EST, 12:01pm PST).
In a release Microsoft said: "To start playing your Xbox 360 games on Xbox One after this time, refresh your Game Collection to see your pre-purchased, digital Xbox 360 titles from the Backward Compatible title list in your ready to install queue, or simply insert the disc for a supported Xbox 360 title and download the game to start playing it on Xbox One."
A full list of available titles was revealed earlier this week, and while most of the 104 games are Xbox Live Arcade titles, there are some big names in there. Including: Call of Duty: Black Ops, Fallout 3, Mass Effect, The Gears of War series and Borderlands. More games will added in due course.
