Also playable: Sven Co-op

• Every Sven Co-op map — the full index, with author, difficulty and community rating.
• How to play Sven Co-op online — what the mod is and how to start a map in a browser.

Frequently asked questions

Is Combat Skirmish free?

Yes — completely free. No download, no signup, no payments.

Do I need to install anything?

No. CS 1.6 runs in your browser via WebAssembly — just open the site and click Quick Join.

Can I play with friends?

Yes. Open the Server Browser, pick the same server, and join together.

What do I need to play?

A modern desktop browser. The first load caches the engine; after that maps stream on demand.

Is this the real Counter-Strike 1.6?

Yes — it runs the genuine GoldSrc engine and netcode compiled to WebAssembly, not a remake. The aiming, movement and physics match the original exactly.

Do I need a Steam account?

No. There is no account, no login and no purchase. Open the site and play.

Can I play CS 1.6 unblocked at school or work?

It runs entirely in the browser over standard web traffic, so there is no game client to install on a locked-down machine. Whether it reaches a given server still depends on your network's own rules.

Can I play Sven Co-op here too?

Yes. Sven Co-op runs in the browser alongside CS 1.6 — browse the co-op maps, host one, and friends join from a link. It is free and needs no Steam client.

Can I play Counter-Strike in VR?

Yes, on PC VR. Open the site in desktop Chrome with SteamVR or another OpenXR runtime running, then choose Enter VR in Settings. Motion controllers aim and fire, and the HUD and menus float in front of you. Standalone Quest Browser and Sven Co-op in VR are not supported yet.

Which maps and modes can I play?

Every classic map — de_dust2, de_inferno, cs_office — plus community modes like Zombie Mod, Gun Game and Surf. Browse all maps and all modes.
