Two decades go by quickly, don’t they? The most innocent days of the mid-2000s brought many things, but the PC gaming world certainly remembers Half-Life 2. Valve’s iconic shooter is considered by some to be one of the greatest games ever created. Those who like it probably already own it. Those who don’t have one now have the chance to get it back. As part of Half-Life 2’s 20th anniversary, Valve is offering the game for free to everyone all weekend.

However, that’s not all. Half-Life 2 just received a special update to celebrate its 20th anniversary. The update combines the Half-Life 2 base game, episode one, and episode two into one package. Additionally, it received a handful of bug fixes and compatibilities for the Steam deck. This is a fairly comprehensive list and can be found on the Half-Life website.

This is just a small piece of a larger celebration for Half-Life 2. There is a real Half-Life Anniversary Sale happens all weekend. Additionally, a special Half-Life 2 documentary was uploaded to Valve’s YouTube account. Everything can be viewed below.

Half-Life 2 is considered an all-time classic game. Ten years ago, it exceeded the Shacknews Chatty Community: The 100 Best PC Games of All Time list, finishing ahead of such luminaries as Quake, Deus Ex and the original Half-Life. When the time comes, he will most certainly be inducted into the Shacknews Hall of Fame. The folks at NVIDIA are currently working with the Half-Life community to update the game with the next Half-Life 2 RTX: an RTX remix project. In the meantime, the original Half-Life 2 is completely free and can be added to your library at Steam. Act now, because it’s back to its usual price of $9.99 USD on Monday, November 18 at 10:00 a.m. PT/1:00 p.m. ET.

Ozzie has been playing video games since he bought his first NES controller at age 5. He has been interested in games ever since, only straying briefly during his college years. But he was called back after spending years in QA circles for THQ and Activision, primarily spending time helping push the Guitar Hero series to its peak. Ozzie has become a big fan of platform games, puzzle games, shooters, and RPGs, to name a few genres, but he is also a big fan of anything with a good, compelling narrative behind. Because what are video games if you can’t enjoy a good story with a cold Cherry Coke?
