Valve just released a new version of Half-Life 2, and it's free right now

Given that it was such a genre-defining game, Valve had been surprisingly hushed this week despite it being the 20th anniversary of Half-Life 2. Consider that silence well and truly broken now, as it has just dropped a two-hour long documentary about the game's development, released a new update for the game to enhance it even further, and essentially created an entirely new version of Half-Life 2 that is totally free to add to your library - if you're fast.
