The Witcher 2: Assassins of Kings, Forza Horizon, Fable Anniversary and Crackdown are the latest Xbox 360 games to be given the Xbox One X Enhanced treatment.

They join Assassin’s Creed, Fallout 3, Gears of War 3, Halo 3, Mirror’s Edge, Oblivion, and Skate 3 as Xbox 360 games in Microsoft's Xbox One X Enhanced catalogue.

Xbox 360 games that are enhanced for Xbox One X run at a higher resolution and 9X the original pixel count on Xbox One X.

"The power of Xbox One X enables the Xbox 360 emulator to showcase the very best version of the game possible with the existing assets – all without touching the game code," said Microsoft.

In addition, a new setting will allow Xbox One X owners to toggle between Xbox One X Enhanced mode and standard backwards compatibility mode.

"Compatibility is important to Xbox, to developers and their games, and our community," said Larry "Major Nelson" Hryb.

"Preserving the art form of video games is part of our DNA, which is why Xbox One is the only console designed to play the best games of the past, present and future."
