Half-Life 2 (not 3): The Orange Box, Portal: Still Alive and Left 4 Deads 1 and 2 have all been run through Microsoft's Xbox One X Enhanced ringer, and were already successful parts of the Backwards Compatibility program, Microsoft announced overnight.

In fact if any of them were in your library, you might have seen them updating yesterday. And they're ready to play better on Xbox One X right now. Here's the official line from the powers that be:

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. Today’s additions join the 17 previously released enhanced Xbox 360 titles like Red Dead Redemption and Skate 3 for a total of 21 Xbox One X Enhanced Xbox 360 games.

Compatibility is important to Xbox, to developers and their games, and our community. Preserving gaming classics is part of the Backward Compatibility DNA, which is why Xbox One is the only console designed to play the best games of the past, present, and future. We’ll continue to deliver on our vision of compatibility and grow our current Backward Compatible library, which includes more than 500 Xbox 360 games, 21 Xbox One X Enhanced Xbox 360 titles, and 32 Original Xbox games, delivering quality, legacy gaming content to Xbox One gamers around the world.

Of course does any of this really matter at all? It's not a Half-Life 3 announcement. Okay, well Half-Life 2 is still pretty fricking amazing and being able to play it again (*sigh*, Valve) enhanced on my One X and giant 4K TV is a pretty good consolation prize.
