Half-Life 2 Now Runs Inside a Web Browser

A developer has published a browser-playable build of Half-Life 2, Valve’s landmark 2004 first-person shooter, hosted at hl2.slqnt.dev and surfaced on Hacker News. The project lets users launch the game directly in a tab with no native install, continuing a wave of demanding desktop titles being ported to the modern web platform.

The submission itself carries only the headline and link, so the underlying implementation details — the porting toolchain, how game assets are delivered, and what hardware or browser support is required — aren’t spelled out in the source provided. Projects of this kind generally lean on browser compilation targets and GPU access to run originally-native code client-side, but those specifics can’t be confirmed from the material here.

The significance is less about the game and more about the browser as a runtime: a full 3D engine executing in a sandboxed tab demonstrates how far web capabilities have come, and raises the usual questions around asset licensing and distribution rights for commercial games repackaged this way.
