Microsoft today finally announced many of the specs for its Xbox Series X. Still, the company also outlined something as important as arguably: how the console will manage backward compatibility. The Series X will support “four generations” of Xbox games according to Microsoft, something the company alluded to last year.

“Our commitment to compatibility means existing Xbox One games, including backwards-compatible Xbox 360 and original Xbox games, look and play better than ever before,” Xbox head Phil Spencer published in a blog post. “Your favourite games, including titles in Xbox Game Pass, benefit from steadier framerates, faster load times and improved resolution and visual fidelity – all with no developer work required. Your Xbox One gaming accessories also come forward with you.”

Cyberpunk 2077 developer CD Projekt Red has confirmed that one such cross-generation release will be their massive open-world RPG. “Gamers should never be forced to purchase the same game twice or pay for upgrades,” said the developer

There is also a new and advanced feature named “Smart Delivery,” which effectively turns Xbox games into universal apps if it is used by developers and publishers. Here’s how Microsoft published:

“This technology empowers you to buy a game once and know that — whether you are playing it on Xbox One or Xbox Series X — you are getting the correct version of that game on whatever Xbox you’re playing on. We’re making the commitment to use Smart Delivery on all our exclusive Xbox Game Studios titles, including Halo Infinite, ensuring you only have to purchase a title once in order to play the best available version for whichever Xbox console they choose to play on. This technology is available for all developers and publishers, and they can choose to use it for titles that will be released on Xbox One first and come to the Xbox Series X later.”

Microsoft promises that in the coming months leading up to E3 in June we’ll learn more about the Series X.
