Major Nelson has revealed
that four Valve developed Xbox 360 titles that were already available to play on the Xbox One via the backwards compatibility
program will be enhanced on the Xbox One X starting today.
The four new titles are Left 4 Dead
, Left 4 Dead 2
, Portal: Still Alive
and The Orange Box
, which brings the total number of original Xbox and Xbox 360 titles that are now Xbox One X enhanced
up to 21.
Xbox 360 games enhanced for Xbox One X run at a higher resolution and 9X the original pixel count. The power of Xbox One X enables the Xbox 360 emulator to showcase the very best version possible with the existing assets—all without touching the game code.
