Microsoft has confirmed that four Valve titles have been enhanced for the Xbox One X, and these include classics like Half-Life 2: The Orange Box, Portal: Still Alive, Left 4 Dead, and Left 4 Dead 2 - backwards compatible titles that were already playable, but now have higher resolutions and enhanced visuals.
Xbox's Larry 'Major Nelson' Hryb shared the good news that the titles will have "9X the original pixel count," which is very exciting indeed, meaning these games join the likes of Red Dead Redemption as Xbox 360 titles that have been enhanced.
Which is the best game of these four though?
