How a 1999 game ends up on a web page

Counter-Strike 1.6 runs on Valve's GoldSrc engine, written in C. That engine is compiled to WebAssembly — a format browsers execute at close to native speed — and rendered through WebGL. The result is the actual game running in a tab, not a video stream of it and not a rewrite.

Because it is the real engine, it is also genuinely light: GoldSrc was built for 1999 hardware, so a modern laptop has an enormous amount of headroom.

What you need

A current desktop browser — Chrome, Firefox, Edge or Safari — and a keyboard and mouse. Any machine from the last decade is comfortably enough.

A mouse genuinely matters. CS is a game about precise aim, and a trackpad will hold you back far more than your hardware will.

Phones and tablets

It is built for desktop. There is no touch control scheme that does justice to a game decided by mouse aim, so we would rather point that out than have you fight it.

What to try first

Any classic map is a good start, or read the guide first if you have never played.
