Four Xbox 360 games will get visual enhancements on Xbox One X when the new console launches next month, Microsoft announced today. Halo 3, Fallout 3, The Elder Scrolls 4: Oblivion and the original Assassin’s Creed will all run at nine times their original pixel count and with expanded color details, starting Nov. 7, thanks to free updates.

Those four Xbox 360 games are already backward compatible on Xbox One, but thanks to a technique known as “the Heutchy Method,” named after the engineer who developed it, they’ll look better than ever on Xbox One X. The method “leverages the power of Xbox One X to let the Xbox 360 emulator present the very best version of the game possible with the existing assets—all without touching the game code,” Microsoft said in an official announcement.
