What "no download" actually means here
It does not mean a stripped-down clone. It means Counter-Strike 1.6 — the original maps, models and sounds on Xash3D FWGS, an open-source engine compatible with GoldSrc, compiled to WebAssembly — is delivered to your browser the way a web page is, instead of installed as a program.
You never run an installer, never create an account, and never leave anything behind on the machine beyond your browser's normal cache.
So what loads, and how long does it take?
The engine is fetched once and cached by your browser, so the first visit is the slow one and every visit after it starts fast. Maps stream on demand: you download a map the first time you play it, not the whole game up front.
That is the trick that makes a decades-old game with hundreds of megabytes of content workable on a web page — you only ever fetch the part you are actually about to play.
Does it play like the original?
Very closely. The engine is built to be compatible with GoldSrc and the game follows Counter-Strike 1.6's own rules, so recoil, movement and hitboxes behave the way 1.6 does — and it plays on the same public CS 1.6 servers the Steam version joins.

Frequently asked questions
Do I need to download anything?
No. Nothing is installed on your machine. The engine is streamed to the browser tab and cached there after the first load.
Is this the real Counter-Strike 1.6?
It is Counter-Strike 1.6 on Xash3D FWGS, an open-source engine compatible with GoldSrc, compiled to WebAssembly. The aiming, movement and physics follow 1.6's rules, and it joins the same public servers as the Steam version.
What do I need to play?
A modern browser on a computer, phone or tablet. The first load caches the engine; after that, maps stream on demand.
