Most of Valve’s Xbox 360 titles are now backwards compatible with the Xbox One, complete with Xbox One X enhancements.
Everything included within The Orange Box are now backward compatible with the Xbox One. That means that Portal: Still Alive, Team Fortress 2, and Half-Life 2 (All episodes) are all accessible via the Xbox One. All of these titles are also receiving the Xbox One X Enhanced treatment, meaning improved visuals and buttery-smooth frame rates for Xbox One X owners.
Xbox 360 versions of Left 4 Dead and Left 4 Dead 2 are also backward compatible, along with all the Xbox One X enhancements. According to Microsoft, players will “see them with the stunning visuals only the Xbox One X can deliver.”
The Orange Box is available for the Playstation 3, Xbox 360 and PC.
