The number of Xbox One backwards compatible titles now number well over 250 and Xbox boss Phil Spencer reiterated once again just this week it’s possible original Xbox games could eventually make their way to the system.
The Orange Box, which was released on Xbox 360 back in 2007 comes packed with Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, Portal and Team Fortress 2.
Xbox One users can now play Half-Life 2 thanks to backwards compatibility.
That said, Microsoft isn’t working on making those titles backwards compatible at present.
