Half-Life 2 Full Campaign Runs in Any Browser via WebGL 2 Port

*An unofficial port delivers the complete game at over 100 FPS with save states and Source console support, no download required.*

A browser-based version of Half-Life 2 now exists that recreates the original campaign using WebGL 2. The port was built in three months by developers Slqnt and 98006. It runs at more than 100 FPS on suitable hardware and includes save states plus console integration.

Players can launch the game directly in a browser without installing files. The implementation preserves the full campaign structure. Console commands from the Source engine remain available for cheats and adjustments.

The project surfaced on July 5, 2026. It stands as a self-contained recreation rather than an official Valve release.

Why it matters

Browser ports of this scale show how far WebGL 2 can push legacy game engines when developers focus on direct translation instead of new features. For engineers the result is a concrete benchmark of what current web graphics APIs can sustain in real-time 3D titles. No company announcement or licensing change is involved; the work remains an independent effort.
