Ranked 5v5: CS 1.6 matchmaking in the browser

Compete is ranked Counter-Strike 1.6 matchmaking with nothing to install. Queue on your own or as a party of up to five, accept the ready check, and play a full MR15 match — knife round for sides, halftime swap, overtime on 15-15 — against players near your rating. The match server is one player's browser, so there is no dedicated server to rent and no launcher to run; if that player drops, the game moves to another and resumes at the same score.

Open Compete — queue, party lobby, leaderboard and your match history.

Also playable: Sven Co-op

Sven Co-op is the co-operative Half-Life mod — a group works through a map together against the game's monsters instead of each other. It runs here the same way CS 1.6 does: browse the co-op maps, press Host, and send friends a link. No download, no Steam client and no port forwarding.

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. Form a party of up to five in Compete and queue for a ranked 5v5 together, or open the Server Browser, pick the same server, and join together.

Is there ranked matchmaking for CS 1.6 here?

Yes. Compete is ranked 5v5 Counter-Strike 1.6 in the browser: queue solo or as a party, accept the ready check and play a full MR15 match with a knife round, halftime swap and overtime. Nothing to download and no dedicated server — one player's browser hosts the match.

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.

Is CS 1.6 still active?

Yes. At 20:23 UTC on 11 October 2026, 4,373 people were playing on 959 public Counter-Strike 1.6 servers, not counting bots. You can browse them in the server browser.

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.
