Half-Life 2 runs in a web browser

Half-Life 2, the 2004 Valve first‑person shooter, has been ported to run inside a web browser. The project compiles the game’s engine to WebAssembly and uses WebGL for graphics. No installation or download is required; users can launch the game from a URL. The browser version retains the original campaign and multiplayer modes. Developers report performance comparable to low‑end desktop builds. The effort demonstrates how legacy titles can be preserved through web technologies. It also offers a convenient way for newcomers to experience the game without a Windows PC. The code is open source, inviting further community contributions and optimizations.
