The 20th Anniversary Update for Half-Life 2 includes:

Episode One and Two Expansions in the box

Half-Life 2 now includes the complete Episode One and Episode Two expansions along with the base game. They're accessible from the main menu, and you will automatically advance to the next expansion after completing each one.

Steam Workshop Support

Browse, install, and play user-created content for Half-Life 2 without ever leaving the game. Look for it in the Extras menu!

Updated Game Content

Every map in Half-Life 2 has been looked over by Valve level designers to fix longstanding bugs, restore content and features lost to time, and improve the quality of a few things like lightmap resolution and fog:

    Fixed pops, holes in the world, fading-out and disappearing objects across the game.
    Rebalanced the lighting across Half-Life 2 to account for playing with HDR on or off, using the original release as reference.
    Cleaner, smoother horizon lines thanks to new radial fog!
    Added higher-resolution lightmaps across the game!
    Removed green glow from the G-Man model's eyes in the opening of the game, and restored the reflective glint as seen in the original release.
    Fixed missing grass sprites and blacked-out models throughout the game!


Updated Graphics Settings

    Choose either the original launch day blood and fire effects, or those created for the episodes, when playing the Half-Life 2 base game!
    Play with only the highest detail models in High Quality mode!
    Get smoother lightmap shadows at Very High shader detail, thanks to new bicubic lightmap filtering!

AND :

From now through the weekend (until November 18th at 10am Pacific) Half-Life 2 is free to own, so if you've never played before, grab it now and keep it forever.
