An unofficial fan project has brought Half-Life 2 to web browsers, allowing players to launch Valve’s classic first-person shooter without installing the full game on a PC. The browser port was created by a high school developer known as slqnt, and the project has quickly attracted attention from the gaming community.

A Browser Version Built in Just Three Months

According to the developer, the browser port was completed in roughly three months. Players can launch the game directly through the project’s website, where starting a new game requires minimal downloads compared to a traditional installation.

The project joins a long history of fan-made efforts to keep Half-Life 2 alive on new platforms. Similar to the many unofficial Doom ports released over the years, the browser version demonstrates another creative way the nearly two-decade-old shooter can be experienced.

The Project Has Already Gone Viral

Since being showcased on X, the browser port has spread rapidly across social media, with thousands of players trying it for themselves.

Community reactions have largely praised the technical achievement, with many applauding the developer for making Half-Life 2 accessible through a standard web browser. Others have questioned whether the project will remain available long-term, wondering if Valve will respond to the unofficial release.

Many players also expressed hope that the project encourages similar browser-based adaptations of other classic games.

Mobile Support Is Limited

Some users have reported successfully launching the browser version on mobile devices. However, the experience is limited because touchscreen controls are not well suited for the game.

While the port can run in a mobile browser, players will need to connect a keyboard to access most of the game’s controls effectively.

Ongoing Updates Are Improving the Experience

The developer continues to release bug fixes and performance updates as more players test the browser port. As development continues, stability and compatibility are expected to improve over time.

Although this is an unofficial fan project rather than an official Valve release, its rapid development and positive reception highlight the continued popularity of Half-Life 2. More than 20 years after its original launch, the landmark FPS continues to inspire fans to find new ways to experience—and preserve—it on modern platforms.
